Before Windows Phone 7 even shipped, I was talking to my Microsoftie friends and said that I thought there was a great opportunity to build a phone that had the best Microsoft enterprise (Exchange and Sharepoint) integration, good free developer tools, and a good app marketplace with better organization and discovery than Apple's. Now throw in great Skype integration and Office support and they could have a good business phone. But if the phone doesn't have Dropbox, Pandora, and dozens of other high-profile apps users are already using on other platforms, that's a hard sell to anyone outside of IT departments. I think there's also a window to build a decent consumer phone with great XBox integration. Make the phone essentially compete with Wii U and have great stand-alone mobile games too. That could be a great phone for twittering teens. You just have to get on other carriers besides AT&T though.
