Blackberry Z10/Playbook Dock

Just throwing an idea out there. What if BBRY made a playbook dock for the Z10? It could use the phone's processor and RAM in a similar fashion to Asus' Padfone and it would bring BB10 to a large tablet format. I know there will be other stuff that has to be worked out but like I said just an idea :D

Oh my gosh I love it! Just plug the Z10/Q10 into a screen with a keyboard, and you've got a laptop. I'm surprised no one has thought of it. I would totally buy it. It would solve my dilemma of me wanting to sell my PlayBook to help pay for a Z10.
