What's going on with Microsoft's Surface Andromeda device?

The last couple of weeks have been rife with speculation surrounding Microsoft's mythical Andromeda device, with recent rumors suggesting Microsoft is close to pulling the plug on its dual-screen mobile handset — understandably throwing optimists and die-hard fans into a panic. Everything from delays to significant hardware changes, to outright cancelations, have been spotted on the rumor mill as of late. So what's really going on?

I've been doing some digging to try and clarify some of the recent rumours reported by several news outlets, to see if we can make better sense of the situation.

ZDNet's Mary-Jo Foley recently wrote a bit about Andromeda and revealed that Microsoft has decided to delay its release to next year, and is also seriously considering canceling the device altogether. This news caught many off guard because just a few days beforehand The Verge had written a somewhat positive article that revealed internal emails describing the Andromeda project itself.

Unfortunately, it is believed that the leaked emails in question are months old, from back when Terry Myerson was still in charge. Many believe that now Myerson is out, Andromeda won't ever see the light of day, which is entirely possible of course. However, I was able to confirm recently on the Windows Central Podcast that Andromeda is still alive and kicking internally, with the only bad news being that its planned release date has indeed been pushed back to next year.

Why the delay?

The question now is why? Well, according to my sources, Microsoft has decided to push back Andromeda's release to give itself more time to improve both the hardware and software. There are a whole lot of moving parts involved when it comes to Andromeda, as it's being built alongside a custom version of Windows 10 specifically for the device and form-factor itself, similar to Surface Hub and HoloLens.

The Andromeda device runs an experience tailored for its unique form-factor, which is built on top of Windows Core OS. This tailored experience is known as Andromeda OS and includes no legacy UIs and bloat. Microsoft is doing the exact same thing with Surface Hub 2, which also runs a custom tailored version of Windows Core OS known as Aruba and built specifically for that large collaborative device form factor.

Microsoft pushed back Andromeda's release to give itself more time to perfect the hardware and software.

Therefore, it's important to stress that Andromeda OS is unlike any version of Windows 10 available on the market today; it's an entirely new Windows OS experience powered by CShell that's built from the ground up for mobile dual-screened multitasking. Because of this, Microsoft needs more time to ensure the OS is well-baked.

Microsoft also needs more time to improve the app-gap on Andromeda, which is another cited reason for its delay. If Microsoft were to release Andromeda this year, it would do so with a platform that has more missing apps than Windows 10 Mobile did. One of the things Microsoft is doing to help combat the app problem is embracing PWAs (Progressive Web Apps.) It's even built a bot that will automatically add PWAs to the Microsoft Store without developers having to submit them first.

Of course, PWAs won't solve everything, but they should be able to step in for the most popular apps and services like Twitter, Uber, and even Spotify if it chooses. The delay gives Microsoft more time to get PWAs into the Store, and I hear Microsoft is going to use this extra time also to improve the Edge engine so that PWAs perform better and eat less battery life.

It probably goes without saying that UWP is also something Microsoft is actively pushing on Andromeda, and apps like WhatsApp are a possible contender for this, but progress on the UWP front is slow, hence the focus on PWAs. Furthermore, I'm told there are other ideas that the company is also considering to help improve the app situation on Andromeda, but I'm still digging for information on that. For now, we know that Microsoft is betting big on PWA, and rightly so.

What about the hardware?

I've seen a few rumors claim that the delay is related to hardware, with some reports suggesting that Microsoft is planning to rethink the device and even change its form-factor a bit. According to my sources, however, Microsoft is not planning to drastically change its form factor. The delay is primarily software related, as the hardware itself was more or less good to go for an October release.

The delay now means Microsoft has more time to "fine-tune" the hardware, and maybe even slip in a newer processor, depending on whether Andromeda's release lines up with Snapdragons processor roadmap of course. I understand that the latest Andromeda prototypes use Snapdragon 845/850 processors, but now Andromeda is coming later, those chips may be old by the time Microsoft is ready to launch the device.

It's worth noting that early Andromeda prototypes used a Snapdragon 835 processor, which was later switched out for the 845. So, Andromeda has already gone through one processor switch internally before, meaning it's not hard to imagine the device going through another one if needs be. A more powerful, optimized ARM chip is never a bad thing.

It's also not uncommon for a device to go through several iterations throughout development. Putting in a newer processor may require the company to rework some of the internals, but outside of that, I have not heard of any plans to dramatically change up the form-factor itself. It should still be a pocketable, pen-orientated foldable device with telephony when it ships.

So when is it coming?

The biggest question now is when can we expect it to show up? The simple, unexciting answer is "when it's ready." Windows development has changed quite a bit since the old days, and deadlines aren't as strict as they used to be. How it works now is engineers working on software features will have a set deadline for a future release of Windows 10, let's say RS5 for example. This usually happens several months to a year or so before that release is expected to ship.

It'll be ready when it's ready.

This gives engineers time to build out a feature, but if the engineers find that they are unable to complete the feature in time, they can just push it back to the release coming afterward. So in our example, said feature is pushed back to RS6, and the team working on it now have an extra six months to complete it. This cycle repeats until the feature is good enough to ship. This is exactly what's happening with Windows Sets, in fact. This is partly why Microsoft is committed to two updates a year as it allows Microsoft to get features out sooner after they get pushed back.

The software delay for Andromeda is with Andromeda OS, which simply won't be ready in time for RS5 now. So, that means Microsoft's next port of call for Andromeda is RS6 (known as 19H1) in the Spring of next year. Even then, Microsoft may decide to hold on releasing it until the fall of 2019, alongside RS7 (known as 19H2) giving the company even longer to make sure everything is good to go and maybe even slip in that newer processor.

It's not plain sailing

Of course, if you've been following along with our Andromeda coverage since last year, you'll know that the possibility of Microsoft killing Andromeda is never far away. As of today, work continues on Andromeda as normal, but that doesn't mean it's plain sailing from here until it ships. Microsoft may pull the plug at any time, as is the nature of internal development.

We also still don't really know who this device is going to be for, and that's because we don't know its full feature-set yet. Who Andromeda is for is going to depend heavily on what it can do. If Microsoft can improve the app-gap, then buying Andromeda is going to evolve primarily around its capabilities, on both the software and hardware front. Hopefully we'll learn more about what it can do in the near future, but for now who Andromeda is aimed at remains a big mystery.

In short, Microsoft has delayed its Andromeda device to ensure a better product when it ships. All of the people I've spoken to on the subject agree that delaying Andromeda is nothing but a good thing. It just sucks that we're going to have to wait even longer before we get to see it for real. In the meantime, what are your thoughts on Microsoft's Andromeda project? Let us know in the comments!

  • I think experimentation approach would be better...release something now and iterate the software quickly....
  • agree
  • Launch with Windows core OS + Android subsystem
  • Analysis paralysis: "Analysis paralysis or paralysis by analysis is the state of over-analyzing (or over-thinking) a situation so that a decision or action is never taken, in effect paralyzing the outcome."
  • yeah, their decision making seems to be more guided by fear of failure...
    they want to wait till they feel there is no risk of failure ...that means wait forever!
    in this age of AI...quick experimentation without betting the farm is the way to go...slow movers won't get a chance :)
  • Let's be honest. This device just isn't that important to Satya Nadella/Microsoft. It's not a priority. By the time this thing launches (if ever) there will already be several Android (and possibly Apple) options to choose from... which will pretty much make the Surface Phone DOA.
  • I'm willing to bet part of the reason they won't release it is bc they don't want people to be disappointed when they discover it's not a surface phone
  • Usually I would disagree with this approach, but since any significant delay would seriously risk Andromeda getting gazumped by an Android device I have to agree. Kinda. A bad release will kill it, but getting gazumped will kill it, so they have one narrow window of opportunity and better get that software going great very soon to take advantage. If they miss that one chance, I see a retrenching on the horizon.
  • Yes, even if they come up with an excellent product at some point in the future..because of the switching cost it'd be difficult to get people to give it a chance....but if they release it now and quickly evolve it...at least it would have a chance of some success...like you said delaying it is same as effectively killing it.. software is never going to perfect...unless you go the apple way by limiting your use cases and tightly controlling the ecosystem...but with Microsoft always wanting to be everything to everybody there is no chance of that happening before it's too late :) I think, If they start open sourcing some components of windows strategically - the software could evolve rapidly...and also make the ecosystem more appealing to the developers... As far as I'm concerned I think Andromeda is going the same way as Courier...I'm looking forward to getting my Note 9!
  • I don't see much of a chance if when the inevitable Android takes on a dual screen device releases, the Andromeda will be killed. That's literally throwing away money. I definitely would not release
  • I don't know, first impressions are really important. Even Apple with its brand couldn't just push out Home Pods unfinished without backlash. Microsoft is already doing very well financially without phones at all, so they might as well wait, they literally have nothing to lose. That said, I can't wait for Andromeda!
  • Apple came out with Home pods AFTER Amazon and Google (and even the slow moving Microsoft) had already released their smart speakers. But, if they were the first ones to release a smart speaker... Apple fans would have loved it and wouldn't have minded those shortcomings :)
  • The first product is relatively meaningless. Its the commitment and iterations that matter. Android proved that.
  • Surface did too, now that I think about it. Nadella just doesn't have any toughness in him.
  • Exactly! Based on the rumors kipman worked on the device...not Panos.
    May be Panos doesn't want the device to be released as part of the surface brand without him not leading the development!
    Hope he doesn't kill it... What Kipman has done with Mixed reality headsets - building low cost devices, bringing all the OEMs on board, etc...
    is going to help Windows MR succeed in the consumer market in the long run!. - even though these first iteration headsets didn't sell well If he really did work on Andromeda...I'm sure he would've done a great job!
  • Yes, I'm sold on this one. The more the delay the more matured product will be when it gets here and it's evidently going to be a game changer of a device both in software and hardware front, of course it deserves some time experimenting.
  • well by the time they get something out...there will be no game to change...game would be over :)
  • I'm cool with the delay.
  • No that would be terrible. It was to be exactly how it was with the original Surface book 2 launch minus the bugs (henceforth why the extended time to launch is also a bonus). It was to be a wow product that is launched already feature complete and with a smooth and bug free (in the realm of possibility) experience. Otherwise the impact will be lost and by the time the product is actually good people would have already forgotten about it.
  • They should make a vídeo like they did with Surface Hub 2 and release it when it's ready. Kill it is the easiest to do, but I do hope Microsoft don't lose again in a brand new mobile market
  • Thank you for the information but I think the 2019 is just disaffirmation surprise everybody In October.
  • I am with you KJW3...it could be a surprise in October.
  • Yeah, that would be great. My Mi Mix 2 is only 4 month old (and quite good compared to other Crapdroids i tried before) but i would sell it in an instant to get a non-frustiating mobile experience.
  • Take a Surface GO, slap on the new-fangled hinge, Adjust the UI, and I'm good. Ok, I'm aware it takes more than this...
  • Yep. Gotta design the packaging too remember. At least, with MS, there's no time needed for advertising development.
  • they did Surface GO because they have to... it's few years late to market! Couple of years ago, apple and microsoft watched in horror as ChromeOS took almost 50% of the education market squeezing them out Two years later apple came up with a cheap iPad to counter google in the education market and now finally microsoft is reacting to Apples late reaction by releasing Surface GO!
  • I think the Surface Go's success or failure will determine the direction of Andromeda. Andromeda will be closer in size to the Go when open as dual screen but it would most likely have a more usable touch interface. The current version of Windows 10's tablet mode is just awful and unusable compared to Windows 8.1 and Windows 10 mobile. I think Andromeda has been pushed back because touch and pen functionality in addition to the lack of PWA development doesn't make this device viable yet. A pocket version of Windows will need to have the usability interface of a phone/tablet and the basic functionality of Windows. By doing this, whatever UI Microsoft comes up with Andromeda, it will change the way Tablet mode will work on desktops, laptops and tablets.
  • LOL, if apps haven't happened yet, they aren't ever going to.
  • As a web and mobile app developer, I can assure you that PWA's are getting tremendous attention in my field of work. The potential PWA's have for flattening the code base, allowing devs to target one very familiar framework for all platforms is extremely appealing. This is especially true for the sort of stuff I specialize in (i.e. business oriented applications). I get it that certain types of games, apps delivering certain types of multi-media, etc. have specific 3rd party dependencies, that call for platform specific (i.e. IOS, Android) implementations. But, for a great many commonly used apps (i.e. Facebook, Twitter, WhatsApp, Snapchat, budgeting apps, task management apps, etc.) eventually going the PWA route makes so much sense it is almost the only way to go (especially now that Apple is increasing PWA support in WebKit).
  • Thanks for your perspective. I own a small business and I've been unable to join the app world due to the expense of developing multiple apps for the various platforms (mobile, tablet, and desktop). I've been tempted to go from my Idol S4 (after 2 yrs w/ 950) to Android in order to pick up a single app that would be useful (Comcast Biz), but I can live without it, especially since it won't change anything other than that one app access on one device. My business "app" needs are satisfied via our websites, but a single PWA that makes it into the various "stores" would increase our existing client outreach a hundredfold and make the marketing side a game changer. I hope you're right -- and I hope my little example of how it would benefit one small business spurs you onward!
  • Oh, man.. It's always something.
  • Now Samsung is going to beat them with a single folding display in early 2019. It will immediately make Andromeda look obsolete. No way they release this device after Samsung unveils their true folding phone. By late 2019, Samsung will supposedly have the mainstream second generation ready to go. It will make Microsoft's job seemingly impossible unless they have some truly magical interface. I bet Microsoft still uses the Andromeda design, but it will be dual 8" or 10" screens with Intel processors. It will use a full version of Windows 10 with some new interfaces. That is my prediction.
  • All in time for competition but it seems Apple is the one lagging behind, they are launching something similar in 2020. I have no doubt this Surface Ultramobile PC will shine no matter what Samsung has to offer. You'll see.
  • The Zune shined too. Being early matters.
  • Two separate screens will not be impressive next to a single folding screen. Not at all. We already have dual screen folding phones. It isn't a very useful form factor.
  • There used to be an old commercial that read "There'll be no wine before its time".
    Looks like that's where we are.
    Sad, but I understand.
    What I don't understand is Microsoft's exit from the mobile/phone arena.
    They could and should have kept W10M alive until Andromeda was ready.
    It's not just about profits.
    Loyal customers are important.
    Too many self serving egos can really spoil a company.
  • They decided to allocate the W10M team towards Android/iOS smartphones. MSFT figured that they would never have built significant market share. I think MSFT felt they could gain more smartphone users adopting office/outlook/cortana on these platforms than trying to pull people out of iOS/Android and into W10M.
  • With a new product you don't target everyone. You target the early adopters. The people willing to take a risk on your product. They will be the ones who show off the device to the skeptical mainstream. The skeptical mainstream will ask questions, see it in action and if it works for them, then they will buy your product also. You have a success.
    Windows phone never made it past the early adopter stage. Microsoft then made the next step far more difficult for themselves because they burned a large part of their early adopters by abandoning them. These early adopters are much more skeptical now, and winning them back will be difficult.
  • Regardless of the number of slick never-before-seen features, whether it's inking or dual screen or camera related, it needs to be a true pocket PC that can double as a phone for it to have enough immediate success that MS doesn't pull the plug. I don't think most people want to carry around an additional device but if they can replace a laptop/tablet and a phone, then MS is onto something. That means good Win32 support (despite Zac's and Dan's personal crusades to rid the world of it), good "traditional" input (touch/keyboard/mouse), and good smartphone functionality (apps however they get there, decent camera, telephony, good battery life). Anything short of that will probably be DOA. Consumers, all types including business, won't understand how it's supposed to fit into their lifestyle and MS probably won't be patient like they were with Surface and give it 3+ iterations to find its footing.
  • If it is a Windows 10 device, you should be able to connect to a hub/bluetooth for keyboard/mouse/display. Surface Go LTE is the mobile Win32 compatible productivity device. Does anyone know when I can respond to a text that pops up on my PC?
  • I have been answering calls and texts on Windows using Google Voice. That has been available for years. Why wait for another half baked Microsoft service?
  • I'd be so happy to pay for skype if I could port in my number and have it do the forwarding magic google voice does. We read people here complain about MS killing products. I'm terrified Google will kill off Google Voice, just like google reader, google notebook, igoogle, discussion search, etc. Do that forwarding thing along side VOIP, bundle it with O365 and I'm in. Want me to buy a cortana speaker? LOL. No. Mix a 'smart speaker' with something like an Obi200 that works with Skype and you'll have my attention.
  • Unless the Go has telephony, transforms into a usable form factor for calls, and uses an ARM chip or Intel cooks up something special for battery life, then it's simply a smaller always connect 2-in-1. While pretty cool, not the same thing
  • Agree with this.
  • I reply to my texts all the time on my computer through Cortana. Can't start a text there though.
  • Good summary, Zac. I do think this approach is going to bite MS though...they'll keep iterating internally and in the meantime, someone will beat them to the punch with a similar device that is 'good enough', followed by yearly model updates that improve on the initial base device, and the next thing we know, MS will throw in the towel on Andromeda because "someone else has already captured the new market."
  • Considering the troubles that Google is having with the EU for antitrust practices with Android, I wonder if part of Andromeda's delay is related in any way. Does this mean Android's replacement called Fuschia has ramped up development making Android antiquated a lot sooner than later? If so, would Andromeda's delay could cause another race to catch up to Google's offering down the line since the current competition is basically Android!?! Apple is already trying to position iOs as a Mac Os replacement and Chrome will be fully support Android apps soon, That will leave Microsoft's only advantage of shoehorning Windows into a mobile platform a bit far behind the competition.
  • Like i said before, MS has to get this right on the first take; it's frustrating for us forward thinking, open-minded enthusiasts who see the possibilities. But at least we were given some solace in the fact that the OS is the issue and that they are working to refine it and the app situation.
    And speaking of apps, i think people are way too hung up on apps as it is. Technically, most people only use up to 12 apps (not games) to all, regardless of how many they download. Making sure the big names are represented is important lest we forget many smart devices launched without app stores in the first place. Apps fill in gaps that the OS doesn't handle by default. Full Windows 10 will satisfy legacy demands; PWA and UWP should, in theory, fill in the mobile apps somewhat.
    This device has to make sense to be built. It has been built so it makes sense to a number of people already. It has to be performant; the newest SnapDragon chips should help move that needle.
    It should support e-sims out of the box; this is dependant on carriers. It should be 5G ready - while this is dependant on carriers, the Qualcomm modems are ready now.
    It needs to be Office friendly and supported - with cloud sync in Office (mobile) apps and One Note/Todo gaining traction, this is getting compelling.
    The gotcha would be either: wooing Android developers to UWP/PWA (see the 95/5 split now as an incentive) OR incorporating a modern day BlueStacks to run Android apps (mostly just java anyway) natively or emulated as part of the CoreOS.
    Imagine your 'vital' Android apps on the device you can do real work on!
  • Not sure about your use, but I struggle to do "real work" on the small Surfacebook screen. Dual 6" screens with no keyboard, trackpad, or native Windows apps will make it nearly impossible. You won't be able to do anything not already possible on Android or iOS. Pointless device, Nadella is right.
  • The preferrable input source of Andromeda isn't keyboard/mouse/trackpad, it's digital ink. Why do you think Microsoft is investing in ink to text support in Windows' text boxes?
  • Inking flat out sucks. It is handy to sign a document on the rare occasion, but it isn't a viable input method for Windows. Just an auxiliary feature. Maybe you have data that says otherwise, but it certainly doesn't seem like a popular feature.
  • Meanwhile the mobile market continues to innovate, and a number of other manufacturers (Samsung, Huawei, Lenovo) are expected to release dual screen Android handsets this fall. Time is not in Microsoft's favor.
  • Samsung is not releasing a dual screen device as far as I have heard. Their's will be a single folding screen, making Microsoft's dual screens obsolete.
  • There is one difference now that we didn't have before and that is Surface Go, a proper, windows 10" tablet. Theoretically speaking if both of andromeda screens are 5" so opened up it will be an approx 10" tablet. So this way with the Surface Go they can optimise the tablet UX, which has been lacking in Windows 10 for awhile. It's gotten marginally better but it's still lacking. Also another factor in play is Charlotte Yarkoni, she is the Vp of growth and ecosystem. By Build 2018 she was at Microsoft for a few months and the developer sessions were more UWP focused compared to previous years. I wish Microsoft had focus on UWP alot more back then. We wouldn't be discussing the app gap if they did. Never the less these two new factors need to be taken into account. So If Andromeda is delayed so we get a more polished product and we avoid a 950 / 950XL launch fiasco then I'm all for it. If it turns out to be just lip service... all I'll say there aren't enough swear words in the dictionary 🤣😂 to be able to convey my frustration.
  • Two 5" screens do not make a 10" screen.
  • @bub78.
    Really? If you half a 10" screen what do you get? Or 10 divided by 2. I'll wait. Screen size in this context is measured diagonally. The simplest example is a book. Top left corner to book spine (bottom right) + top right to book spine (bottom left). Plus I did say approx 😶.
  • Right, measured diagonally. When you put two 5" rectangles (diagonally measured) side by side, the new diagonal measurement is not going to be 1 to 1. Look at the Axon M. Two 5.2" screens become a single 6.8" screen. You are definitely wrong here. To make a single 10" screen, it will take dual 8" screens depending on the ratio.
  • I disagree. The axon m doesn't become a single 6.8" screen. It would be completely out of porportion.
  • ZTE disagrees with you: "Two identical Full HD screens combine to give you a stunning 6.75" tablet-like display. This Extended Mode lets you play games or watch your favorite shows on a larger screen, when and where you want to." https://www.zteusa.com/axonm/
  • @bleached. As that indeed what ZTE has said on their website. I have no qualms in admitting when I have made a mistake about what I said about the AxonM. However I still question their methdology.
  • The ratio fully opened would most likely still be 3:2 and that's if the Surface team makes a device. Andromeda is starting to sound less likely a Surface specific device but another platform that oems will have a license to make their own offering. A 3:2 ratio would be able to fit the 18:9 ratio when folded that popular flagships have now.
  • If you want to say an 8" screen is roughly the same size as an 10" screen. Otherwise, no.
  • "If you half a 10" screen what do you get?" You get a 7" screen. "Or 10 divided by 2." No. It does not work that way. "I'll wait." I will wait for you to test this. Take ANY screen you have handy. Measure it. Divide it in half horizontally. Then measure that half diagonally. Half of a 24" screen is 16.5". Get it yet? Its even worse if you halve the screen vertically. A 10" screen becomes an 8.75 inch screen folded in half along the long axis. The 24" screen becomes about 21" when folded vertically.
  • Yay! a mathematics lesson just what I was waiting for - I wasn't bothered to do mathematics after a long day haha. I guess none of you considered what the average joe would do? They would take a device and overlay ontop of the Surface Go and say it's a 10". To sell the average joe on a idea, you need to get them imagining how it would work and benefit them. So relax, also see Brian Mueller's comments.
  • (Deleted unnecessary comment.)
  • Thats not how it works. "There is one difference now that we didn't have before and that is Surface Go, a proper, windows 10" tablet. Theoretically speaking if both of andromeda screens are 5" so opened up it will be an approx 10" tablet." see screensize with too screens put together link: https://imgur.com/a/OD99kBH Bonus info: This size is from one of their patents. So they also had this size in mind!!!
  • I said approx and you need to take into account porportions and how screen size is measured (diagnally). Since it's like a book, so half and half.
  • My phone is about 5.6" x 2.8". Pretending it was a bezel-less display it would be a 6.2" screen. If 2 of them were slapped together it would be 5.6" x 5.6". Using 7th grade math we find the diagonal is about a 7.9" screen, again without bezels. This is a dumb thing to argue over. It's the Pythagorean theorem ffs.
  • Maybe MS will use the 3:2 ratio like they do on the rest of their surface line. a 10" device with no bezel would be around 8.34 x 5.56 inches when unfolded. Folded would be 5.56 by 4.17 which would 6.95" device but would be a weird aspect ratio
  • And also 4+ is way too wide to use one-handed comfortably so using it folded becomes fairly pointless & sort of negates the purpose of folding it..
  • Of course they could use the ISO A4 paper standard as the size. It is designed to be folded in half and retain the same ratio. So folding an A4 paper in half would give you an A5. I think the ratio is 1: 1.618. An A4 sheet 8.27 x 11.69 or a 14.32 diagonal. Folded in half would give you an 8.27 x 5.85 or a 10.13 diagonal. or an A6 which would halve it again 5.85 x 4.135 for a 7.16 diagonal. The last two seem to be the best combination, but that would still be a pretty big mobile device. Maybe they will start somewhere less than A5 then fold that in half to something that is closer to 6" diagonal.
  • Good thinking
  • @Brian Mueller. Thank you.
  • @bub78. I'm not arguing over it, you're the one who has the issue here bub78. There is more than one why to look at things. In this context, it's not about mathematics but selling an idea. To do so you keep it simple, why do you think I kept refering to it as a "book" and used book as an example. The average joe does not give two hoots about pythagoras theorem lol. So relax :)
  • You think Microsoft should sell an idea that is mathematically impossible? If you read Mueller's comment above, the screen would need to be 7" to unfold to 10" and that is at 3:2, a weird ratio for a phone.
  • And way too big to be useable. Tired of reading comments about a 9" or 10" folding screen that'll just magically be pocketable. Try fitting a 5.5 x 4.2 inch device in your pocket & see how comfortable that is. So dumb.
