As we just hinted, IE6 on Windows Mobile 6.5 is going to be a sight better than it currently is on the WM6 Sprint Treo Pro. There are plenty of reasons for this. Stuff you likely already knew: it has a better, touch interface and it will be on 6.5, which will only be on devices with plenty of RAM, which will mean that its nigh-insatiable appetite for memory won't be as much of a problem.

But wait! There's more! We caught a couple of nice tidbits from the excellent MIX09 Windows Mobile presentation video featuring Loke Uei Tan (who is currently taking one for the team. Go Lokeuei!). Namely, IE6 on 6.5 is more of a "hybrid" than it is a straight mobile implementation of IE6. First up: it actually supports PNG alpha channel  transparent graphical elements ftw! The other change is that it's using the javascript engine from Internet Explorer 8 which should add some compatibility and performance to the entire thing.

Of course, that doesn't mean we're happy about the rendering engine. I've personally lost time roughly equal to the Jurrasic period to IE6 compatibility. That movement to get web designers to give up supporting IE6 altogether (thanks Rich!), it didn't spring up out of nowhere. The lack of tabs is also disturbing.  But hey flash support, right? Right?

Up to now I haven't much cared about rendering fidelity on mobile. As these devices get more pixels, I suspect it will begin to grate more. What say you?
