Sony announced a while ago that it will be introducing two Android tablets, S1 and S2. S1 would be your typical Android tablet with dual core processor running Android Honeycomb (3.0). However, the S2 is unique in that it is a dual-screen clamshell tablet... almost like a Nintendo DS XL. The S2 will sport two 5.5" 1024x480 screens in addition to the dual core processor. Both would be PlayStation Certified.
Germany's Golem website has posted a video on the S2. It is very short but gives an idea on how it works.
Rumored pricing is $599 for the S1 and $699 for the S2. Yikes!
