points out this InfoWorld review of the BlackBerry PlayBook, "an 'unfinished, unusable' tablet from RIM. 'At the core of it all, the design of the PlayBook as a BlackBerry-dependent device was simply a boneheaded decision by executives who hoped a hit product might entice more BlackBerry sales,' Gruman writes. 'Why RIM chose to ship the PlayBook in such a state is unfathomable. The iPad 2 and Xoom have been out for weeks, so there's no heading them off at the pass. Instead, the PlayBook debuted with all eyes on it — but instead of a world-class performer, we got the homeless guy who plays air guitar in front of the mall.'"
