> "BlackBerry integrated all communication channels into one place so it didn't matter which platform you were messaging someone on" Windows Phone 7 did a great job at this.

Sadly it was anathema to companies like Facebook who absolutely want you to enter their app and absolutely don't want to be API providers for a centralized user experience controlled by an OS vendor.
