Pulled from Wiki "and strictly controlling the hardware it runs on."
I remember there more about it being an ad serving machine and to keep the experience consistent by preventing OEM's from customizing the OS. Thankfully communities like XDA, PPC-Geeks, and PPCKitchen exist, so maybe, I'll try it out after its has time to mature. For now, I think I'll stick to WM6.1 (Never really took to the 6.5 interface).
