Another tablet device and another OS. Things are hotting up with BlackBerry entering the arena with the Flash Player 10.1 and AIR 2.5 enabled PlayBook.

It looks like this device will pack a punch, with a 7-inch screen, 1GHZ dual-core CPU, 1GB of RAM, support for hardware accelerated video and an HDMI output that can apparently send video to dual displays. The device also comes with USB ports, and a front and rear-facing camera.

Pricing and the release date aren’t available yet but this is another exciting opportunity for Flash developers and could provide another huge market for delivering Flash content to.

From the video, the OS looks really gorgeous. Fingers crossed for this one.
