BlackBerry PlayBook demoBlackBerry-maker Research in Motion briefly demonstrated its BlackBerry PlayBook tablet today on stage at Adobe’s MAX conference.

We heard from Adobe earlier today that it had teamed up with RIM to bring its new AIR application platform to the PlayBook, and the company also revealed that parts of the PlayBook’s user interface were built with AIR.

Given that RIM couldn’t muster a live demonstration of the PlayBook at its own event in September, it’s surprising that the company handed over one of its most anticipated demos to Adobe. Adobe’s AIR software developer kit (SDK) apparently has some deep hooks into the PlayBook’s operating system, which should let developers easily create some powerful applications.

RIM co-CEO Mike Lazaridis hit the stage to show off the PlayBook. In the video below, you can see him flip through the PlayBook’s home screen (seamlessly, I might add), launch a web browser, and play a Flash-based YouTube video in high-definition. “We’re not trying to dumb down the internet for a small mobile device. What we’re trying to do is bring up the performance and capability of a mobile device to the internet,” Laziridis said. “We’ve worked together closely to get Flash 10.1 player inside our browser with full stage video.”

While it’s a short demo, it at least lets RIM show to the world that the PlayBook actually exists — proving some naysayers wrong.

Update: RIM has put up a longer video of the demonstration, find it below:
