some insane developers from the XDA-Dev community have managed to get the latest version of Android (m5) running on a HTC TyTN II. See the video below to see Android running on top of a cooked Windows Mobile 6.1 build by the powerhouse of TyTN ROM Cookery: Dutty. The flashy part is that this isn't a complete replacement for the Windows Mobile environment. Basically you load up linux “like an app” which itself loads up Android.

The idea is really nice. Expect Android to be made semi-available on pretty much every Windows Mobile platform, which is powerful enough. Now being able to do so with anything resembling stability or safety for the average user, that's probably a way's off, so handle with care, folks.
