I've used nothing but Blackberry since entering the smartphone genre, so i'm not very familiar with any other OS. I do use opera on my BB though and enjoy that. Does PIE come with a flash player? Does it support embedded media?
The biggest reason for me wanting BB connect, is to make the swtich from Blackberry to a WM device as smooth as possible for my wife. I figure if some of the features she needs to use are more familiar to hurt, I'll get less calls at work asking me how to do this, and how to do that, lol.
