OK, so since they run the same software, that means a "developer" device is one with a keyboard, and maybe a larger screen, i don't know, and a "consumer" device is keyboardless... That's maybe because developers usually have much more friends than the average consumer, and sends more sms and e-mails to everyone. Oh, wait, no, that's because developers type their programs in the device itself!!...

What else, the developer device has a better or a worse camera? Is E7 the "developer's" N8?
