I am still rocking the Priv and love it for the slide out keyboard. The phone still manages to be thin with great battery life. The two things I do not like about it are that the keyboard does not have the raised bumps, nor does it have the tool belt which I insist they could have integrated, albeit in a miniature fashion.
The KeyOne interests me greatly, but again no tool belt. I realize the tool belt makes most sense with a BB10 phone, but they should be able to put some software together to give it meaningful and similar functionality. The absolute deal breaker for me on that phone is the fixed keyboard which means VR is out of the question. We will see how the other phones look. The bottom line is that if you are looking for a BB phone with a keyboard, the tool belt is an essential component. Otherwise it's just not the same. A pity this was not understood.
