One real problem I see with wp7. They don't have a tablet and don't have plans for one. I'd go so far as to say that that UI doesn't port to the Tablet form factor for sh*t. Everyone who's got an iphone likes the ipad because it looks and works like the iphone. Everyone who has and android phone likes the android tablets for the same reason. Even the Windows mobile users could convince themselves that the windows 7 or windows ce tables were similar to there phones(even if not true), but what tablet are the WP7 users supposed to identify. That means that if I'm looking for a phone and a tablet i'm probably looking away from M$.
Tablet ??? Jeez...give me a break !
At least pre- I-Pad tablets functioned as a small notebook, and do NOT require a contract to own or use. IF you want a tablet to have phone capabilities, then WHY take away the PC interface so that you're now effectively reduced to using whatever the Carrier or ISP or Google allows you to use?
After all, the APPS that Apple and Droid are offering you (for profit), are rudimentary and inferior to full scale PC software programs.....and do you REALLY want to carry around a tablet to make a phone call ??
A POINT to offer here: Until your carrier has a full fledged 4G network in widespread operation, tablets will be severely restricted....even MORE than what some think applies now to Win7 phones.
MS took the inevitable plunge towards ENDING the previous WinMo OS. New hardware and capabilities certainly require it.
IMHO- Pretty icons and GUI's work nicely for handheld video game platforms....I value functionality and productivity first.
The adaptive nature of W7 OS and the clout of M$ hardware partnerships bode well for it, AND this Forum.
