iOS, Android, and Windows Phone 7

Clearly iOS and Android are getting the most attention in the mobile OS arena, but Windows Phone 7, surprisingly, is providing unique features that improve user experience in some areas. I actually bought a Windows Phone 7 device instead when I visited an AT&T store to purchase an iPhone 4. I have been an iPhone users for about three years. I was attracted to the content-rich system interface and non-discriminative integration of non-Microsoft services such as Google and Facebook contacts.
