We all certainly remember what happens when sites doubt Gizmodo’s “reliable sources” — Steve Jobs’ health, anyone? As such, a particularly interesting rumor emerged this morning that Apple tablet hopefuls might want to take note of. Citing “a source that has always been 100% reliable”, Giz claims to have been informed that Apple is currently working on 13-inch and 15-inch tablet models in addition to the 10-inch model that is all but confirmed by now.

Thanks to some intrepid reporting by our friends over at Gizmodo , we can finally see just what the rumored gScreen Spacebook will bring to the table. The gScreen, which has been created by Gordon Stewart and his Alaska-based cronies, will offer about 30-inches of screen space when you’ve got both screens active, and is aimed at professional designers, filmmakers, photographers and others that hunger for screen real estate. These beasts will run Windows 7 and will be powered by an Intel Core 2 Duo processor.
