If you're in the market for an after Christmas deal today we have just the thing. CowBoom is offering up a pre-owned 16GB BlackBerry PlayBook for just $89.99 + $5 shipping. Similar refurbished units sell for upwards of $139 on other sites, so this is a pretty good deal if you're in the market for a PlayBook. The 16GB wifi-only model comes with just the PlayBook and charger - no neoprene sleeve, USB cable or getting started materials included (but who needs them anyway). Head over to the link below for more info and to purchase.
