If you think that the largest display for the tablet is 10.1 inches, just wait till the MWC 2012 in Barcelona this coming end of February - 11.6 inches!
However, this was still rumours flying around in the Web. The details speculated is that this new Samsung Galaxy Tab's resolution could be 2560 x 1600 pixels - 4 times as many pixels! The processor might be the new Exynos 5250 chipset with dual core processor at 2 GHz.
All this are based on a Samsung tablet shown off at some event in January in Germany; but it was merely a concept.
It would run Android 4.0 Ice Cream Sandwich for sure, which also implies that there would be fewer ports. It would apply the S Pen stylus for handwriting. The camera could either be 5 or 8 MP, the memory 16 or 32 GB. 3G is so blase these days with LTE in the works. WiFi, GPS and Bluetooth would be present as expected as standard these days. Other features could include NFC and DLNA.
