Work it. Anywhere. Any time. Those were the fighting words behind the BlackBerry Mini Keyboard promo shots we showed you a few days back. Now, backing up what we'd heard, RIM's officially (and very quietly) taken the wraps off its new PlayBook add-on, with a shipping date of March 23rd and a $120 price tag. The Canadian outfit is pushing this peripheral on the business-oriented consumer, but there's nothing keeping the average Joe from dropping some hard-earned cash on it. Folks looking to pair up the physical keys and multitouch trackpad with BlackBerry's revised OS can do so by heading over to its online shop. In the meantime, you can get acquainted by checking out the video tour after the break.
