I believe Windows NT is wonderful as well. But it wasn't designed as a real-time OS, whereas CE was; hence the comments that CE was "scrapped" for NT in Windows Phone 8.

The lack of real-time handling probably won't have much impact on the phone platform, since users (the primary interface consumers of the OS) don't operate anywhere near "real-time" anyway.

It's not a lot of work to make Windows NT real-time. Back in the time of NT 4.0 there was a modified kernel that was hard real-time (as far as I can remember).

This is true. I think most of the RT stuff i.e. GSM/3G stuff is offloaded onto dedicated devices.
