I really wanted this to be good. Fantastic Idea - poor execution.
If the 2 screens had met edge to edge it would have been perfect for both ebooks in portrait, and movies in landscape.
Would have got double bonus points if it could fold around 360 to put the screens back to back for reading, kinda like having a Broadsheet and Tabloid paper in the same device.
Seems we reached the cutting edge of hinge design 15 year ago on the psion revo and its been downhill ever since.
Although Im wondering if Sony may have a problem syncronising the screens perfectly which may explain the movieplay back decision.
