This article seems pretty interesting. I was wondering how the keyboard was gonna work, so somehow I wouldn't be surprised if the phone in general was a flop mostly because of this keyboard. I personally don't want to get an iphone because I want to stick with sprint and I hate the fact that you can't add software, but this is just one more reason I can't see myself getting one.
