A research analyst seems to have stumbled upon some knowledge about the rumoured BlackBerry tablet, and claims that it will feature a 7-inch touchscreen (the previous rumour had it pegged at a 8.9-inch screen), and a 1GHz processor, along with both back and front cameras for video chat. We’re starting to thing of Cisco’s Android ‘mobile collaboration ablet”, the Cius, and how it might be the biggest business competition that the BB tab might face in the future. The same analyst, an Ashok Kumar, also let on that the tablet would launch only by the end of 2010 at the earliest.
