In a small post on his MSDN blog, Microsoft's Mike Battista let us know about the recently updated Weather app which hit version 2.0 yesterday. Your response to it has been overwhelmingly supportive of the new version with many giving it high praise.
What's interesting though is how the app was redesigned from "the ground up" to take advantage of the new Tango guidelines:
"In addition to having new features, this version was architected from the ground up for performance following many of the guidelines I call out in my recent blog post Optimizing Apps for Lower Cost Devices.
I encourage you to follow the same performance/UX principles demonstrated by this new Weather update. Following these principles will ensure your apps perform great regardless of the device."
Lead by example. Granted the app is hardly pulling a lot of info but it's still very fast. And it's nice to know that those on Tango will get the same experience. So devs, heed Mike's advice and take a second look at your app and performance using those guidelines. For those curious, here is a listing of Tango limiations.
