@Byron. I have several apps published but none with Microsoft. Was wondering whether to go or not but still not convinced. Did they ever give you that free phone? I do resent having to pay $100 when they are the last guys in. We're taking a chance with them. Google is $25 and Palm is free. Apple can justify it. Microsoft can't.
@Migal, you sound like one of those Blackberry guys saying how their BB does everything the iPhone can while accepting the mediocrity of their platform. Never used Win 6.5, but darn (based on the reviews I read), It's not something to be proud of.
