I'd be shocked if they lose backwards compatibility. One of the major things about WM is the software, I'd bet if you searched out all applications that run on Windows Mobile (things from PocketPC 2000 +)I'd bet it would beat out the iphone list.

A bunch of them won't run due to display res but, most of them should and other minor issues but, over all most of them should run.

It's just like Windows... I still have on a CD (ripped from floppies), a Windows 3.1/95 Monopoly game, it was just very simple, small and it works. I installed it on Windows 7 the other day, guess what, it still works.

I'd deal with it if it happend but, would not be happy about having to rebuy all these apps (games, apps, etc)
