Looks like Mobility Insider got their hands on a BlackBerry PlayBook and reviewed it. The question is whether or not this is an early build or a production build. They apparently are going to post a longer video in the future so we will have to see what else they show that has not been shown already.
Here is their summary of the review:
The BlackBerry Playbook is the iPad contender. If you are currently a BlackBerry user, the fact you can soon get a tablet that offers better all around specs and features without additional data plan equals slam dunk. If not a BlackBerry user, you still have more to gain from this device and data options outside of WiFi only. Since this Tablet comes “Enterprise Ready” out of the box, expect it to take the Enterprise world by storm. So many companies are toying with the idea of how to release iPads (and now Android tablets) into their environment with all the security risks and lack of control. IT can finally breathe with a secure tablet coming out, leveraging RIM’s best-in-class security platform and control.
