Integration of Services: And here we see where Microsoft can blow everyone out of the water. It's a funny feeling, scrolling down the apps and realizing that yes, all of these apps and services were created by the same company! Together at last! Zune, Office, Windows Live and Hotmail, Xbox Live--all are pilars (or "Hubs") of WP7--meta-apps for certain activities that can hold additional apps. And the main third-party service focus here, Facebook, is integrated quietly but smartly. Status updates pop up everywhere--not in your face, but just a side-swipe away. All of your contacts have their Facebook photos associated. You can write on people's walls, if that's your thing, unobtrusively from the contacts app. Individually, each service could stand up to its own mini-review, but overall, the general integration is a resounding success.
