The last time I looked, There was a version of a firmware flash for Windows CE 7 for the VIA WM8650 netbook. I've also read that it will install on 8650 tablets, but doesn't support the touchscreens and in many cases, doesn't support built in wifi...hence making them useless.
I've never seen a CE emulator for Android...and there are a lot of screen hacks to make Android behave in a Windows fashion...but of course it is stil Android and doesn't run Windows at all...just looks like it. You see it a lot with Android tablets that look like Windows 8.
You can certainly find videos on YouTube that show things...they show a lot of prototype tablets running Embedded Comapct 7, but you have yet to see a release of one for sale. On the other hand, you see a lot of YouTube videos showing alien autopsies as well...so I guess it makes sense after all.
I've never seen a CE firmware flash for your CPU however....
