Looprumors claims that Apple is poised to release a "Mac Communicator" device, which is designed to be an accessory to those who already own macs.
Apple will gear this new device at those users who already own Macs. The iTablet will run its own version of Mac OS X Leopard, specifically designed for the device. The iTablet will interact with other devices better than an iPhone or iPod. Users will be able to screen share with their home or work computer from a remote location, video conference with other users, and information suggests the iTablet will have beaming capabilities.
The remainder of the rumor reads like a summary of circulating patent applications over the past year, but without many specifics. LoopRumors has had a spotty accuracy record in the past.
