A research note published by Ashok Kumar, a research analyst at Rodman and Renshaw, mentions that RIM could launch a tablet computer not unlike the Cisco Cius but smaller than Apple's own iPad.
The device, which is likely to be aimed at a professional audience, may have a 7-inch screen, a 1GHz processor and two cameras which would allow video conferencing.
Kumar puts forward the Armada 618 as the most likely processor to be used for a possible RIM tablet, which means that the latter may also offer native 3G compatibility, hardware acceleration and support for 1080p video playback.
Rumours did emerge earlier this year about project Cobalt or BlackPad, one RIM tablet device with a 8.9-inch screen, and which would tether to a Blackberry smartphone for connectivity.
Rather than being a stand alone computer, the tablet would rather be a companion device not unlike the Palm Foleo.
The arrival of Cisco and the emergence of the Apple iPad as the leader in the tablet PC market might have convinced RIM to launch a rival product.
It is only a matter of time before Android tablets go on sale and HP has already confirmed that it will revive tablet format devices based on the Palm OS platform.
