We've only ever seen brief glimpses of the BlackBerry PlayBook in action so far, but a new video posted up by RIM comparing its tablet's web browsing performance to the iPad certainly has us hungry for more. Seriously -- PlayBook pretty much run laps around the iPad while loading pages, and even its Flash performance seems decent, which is a first for a mobile device in our experience. Of course, the video was made by RIM and we're sure the specific pages were picked to make the PlayBook look as good as possible, but that's fair enough -- now if we could just get our hands on one to verify these claims for ourselves, we'd be happy as clams. Video after the break.
