Tablet I have a Playbook and a BB keyboard to go with it. I use it to read stuff and take notes at meetings. I'm working on going paperless. Since I got my Z10, I use the Playbook less for reading but still prefer it for things like magazines and longer reading. I really can't see bluetoothing my keyboard to my phone and taking notes at a meeting. The PB and keyboard is easy to throw into a shoulder bag. If I get stuck with taking minutes, no problem. By the end of the meeting, I'm done.
I think BB needs a tablet, particularly for the corporate market. Companies which want both might decide to stick with one vendor and decide to go Apple or Samsung if BB doesn't have a tablet.
