Anyone who is anyone is rushing towards getting a tablet out right now, including RIM, which is believed to be readying a BlackBerry tablet of sorts that should be on the shelves before the year is out.According to Cnet, Ashok Kumar, an analyst and managing director at Rodman & Renshaw, didn't actually show a picture of the device, but he painted a pretty decent picture of it, giving the impression of something nearer the Dell Streak than the Apple iPad. In terms of specifics, that equates to a 7-inch touchscreen device with a 1GHz processor, the latter rumoured to be a Marvell 1GHz Armada 610 processor, offering full HD 1080p playback, 16-megapixel image capturing and advanced 3D graphics. Nice.Mr Kumar is quoted as saying: 'Research In Motion is trying to pull forward the launch of the 7-inch touchscreen tablet from early next year to year end...with a marginal point of differentiation being the front- and back-facing cameras for videoconferencing.' Certainly the camera option would be a plus compared to the iPad, although, despite Apple's efforts with that technology of late, video calling is still a rather niche mobile pastime.RIM has declined to comment on the speculation, but with such detail doing the rounds, it's almost certainly a case of if, rather than when a BlackBerry tablet will be competing with the likes of Apple, ASUS, Samsung, LG and HP for a share of this expanding market. We await the inevitable leaked shots of the device with interest.
