A couple of industry insiders have reported that RIM is indeed working on Tablet PC models and these are likely to arrive in the market by November this year.

The company recently acquired rights to the domain name BlackPad and this has fueled the rumors that they are going to launch Blackberry OS powered tablets.

The success of Apple iPad has showcased that there is a huge market for a Tablet out there and everyone wants to become part of it.

HP is said to be working on a webOS based PalmPad.

Microsoft is working with partners on Windows 7 based Tablets.

LG and Samsung are set to launch Android based Tablets later this year.

RIM BlackPad might be designed to compliment the Blackberry smartphone. Reports say that the company might allow users to tether their BlackPads with their Blackberries for internet connectivity.
