Awesome... just to clear up any misconceptions- Yes, it will likely be possible to load Android natively on the device's internal memory. Some Vogue users have it flashed to NAND already, effectively removing WinMo completely.

I wouldn't worry about that anytime soon- let's first work on getting a solid Android release with all the functions working before we go deleting WinMo.
Personally, I would always keep both. The only thing you loose is boot time, and Calk here has provided a compromise for now. Nicely done!
