Mystery VAIO tablet visits the FCC

Looks like the folks over at Sony are busy working on a new tablet PC as an FCC filing submitted by the VAIO Business Group shows a tablet that features built-in Wi-Fi and several model numbers such as PCG-31211L, PCG-31311L and PCG-312xxL. No other details were mentioned as Sony managed to keep the photos, user manual and test setup pictures confidential until January 20th. Of course, with CES and January just around the corner, we probably won’t have to wait too much longer in order to find out some details about this device, so stay tuned!
