This may all be true but Microsoft has something that neither Google or Apple has... that is skype. Once skype is integrated fully into Windows Phone; it will be the best communication device off all of them. Skype is the communication tool of businesses. Once skype in rolled into the basic functionality in the same way as: MSN messager, facebook and text messaging, it will be dropdead simple to make a skype call or message with someone as if you are text. Microsoft will steal the market share from Blackberry and the other mobile phones for business and then expand from there.

One of their problems has been a lack of tie ups with carriers. Do you think native Skype capability will motivate AT&T to really push these phones?

Android already has solid VOIP integration via seamless Google Voice integration. It takes over all inbound and outbound calling, messaging etc.
