RIM has now uploaded the full video of its PlayBook's brief stint in the limelight during Adobe MAX yesterday, where Adobe CTO Kevin Lynch and none other than Mr. BlackBerry himself, RIM co-CEO Mike Lazaridis, take the "professional tablet" through its very first public test drive on the keynote stage. The duo run through an MRI scan viewing app -- presumably in an attempt to woo the lucrative medical market -- along with the PlayBook's Air-based video player and browser-embedded Flash player, both of which seem to work pretty well. We also get a quick look at the tablet's multitasking cards, where we see that apps continue to function even from within their card views; it looks pretty nice, but at a glance, it doesn't do any tricks webOS wasn't pulling off a year ago.

Interestingly, the edited video has a number of cuts -- some seem like harmless attempts to cut out boring parts, but there are a couple suspicious ones where we suspect something unsavory happened on the PlayBook or it ran just a little slower than RIM would've liked (of course, with the PlayBook's release still months out, they've got plenty of time to tighten that up while they wait for developers to submit their wares in exchange for a free PlayBook of their own). At the end, Lazaridis expertly skirts Lynch's question of when exactly the device will be released... and he didn't even need a seasoned PR rep standing next to him to deflect it! Follow the break for the full demo.
