The S2 definitely stands apart by virtue of its dual-display construction, reliant on two 5.5-inch displays, one of which occupies what would otherwise be dedicated to a keyboard, were this a netbook. According to Engadget, there is now a name to go with the codename, Sony Table P in fact, its availability being scheduled for next month (September 2011).

The Tegra 2 SoC (system-on-chip) is the platform chosen to power it, while 4 GB of built-in flash storage exist as well.  The obligatory card slot exists, of course, and there is even a 2 GB SD card bundled with the product, or so the report says.

Furthermore, Sony threw in 512 MB of RAM (the processor and video parts would not work without it after all), as well as a 0.2 megapixel webcam. All in all, the dual-display Tablet P has a weight of 370 grams, quite a bit less than the Tablet S (600 grams), which has 16 GB or 32 GB of storage and 1 GB of RAM.
