Shouldn't be a surprise. Anyone that's followed WP7's development knows that they're for real about it.
I personally don't own a smartphone. While neat, neither WM, iOS or Android have impressed me enough to take that financial leap. WP7 has really intrigued me, though. Whenever they get the CDMA devices out, and if it makes financial sense for me, I'm going to seriously consider getting one. And the more they tie in their other services and make good use of the cloud, I think its appeal will grow more and more.
There is room in the still relatively small (less than 30%) smartphone market for iOS, Android and WP7. In fact, for those not paying attention, in just ONE YEAR'S TIME there are now more Android phones being sold than iPhones. Where will WP7 be in one year ...?
