So from my rather unscientific look around at folks working for the tech company I work for in Seattle, I could pretty much conclude blackberry is dead, that most people are using iPhones and Androids getting their corporate email via activesync. Recently, WP7 has become almost as common as BB, but both are still pretty rare.
I certainly manage as well as I did on my last BB with an Android phone with a keyboard. Couldn't really see myself going with a keyboardless phone for corporate email.
