My Dev Alpha C has arrived and it is a beast! The keyboard is fantastic, the battery life superb! I've linked a video below showing an unboxing. Hard-core Blackberry users are going to instantly take to this phone due to the familiar physical keyboard typing experience and the awesome battery performance. More casual users, those who don't mind the touch-based keyboard or media/gaming/entertainment-heavy users are going to stick to the equally awesome Z10 with it's huge HD format screen!
Looking forward to porting my Blackberry 10 apps to the Q10 device!
