I think you may have been drawn in to the MS marketing hype (a bit like some people here have with Nokia's "next billion").
Web, mail, SNS, content sharing, location based services and games, pretty much sums up the mobile handset market and others are doing it better now. Moreover, these are all OS independant and don't need to integrate with a MS "mothership" sitting at home on my desktop/coffeetable.
I guess i'm not worried because I'm "locked" in to the GPL and the last time i checked, that hadn;t cost me anything....
