It looks thicker which suggests that Sony have substantially altered their reader since the T2. To my mind, the most likely cause is a front-light. The buttons remain the same so it looks like it continues to be Android. Can't say I like the jiblet-style buttons, but at least they are still there. This is smart as it separates Sony from the all the other touch-only e-readers. Pesonally I think it looks pretty nice. If it can rooted without bricking and it has a front-light, then I will want one.
