The DPT -S1, which in the past has been nicknamed the Mobius eReader, has a 13.3" screen with a resolution of 1,200 × 1,600. It comes with a dual touchscreen (optical and active digitizer). One can operate this ereader either by touching it with your fingers or by using the included stylus.
According to the specs posted by Sony, it also has Wifi, a microSD card slot, 2.8GB of Flash storage, and weighs about 358 grams.
The DPT -S1 is equipped with an entirely new E-ink screen. The Mobius screen tech is the result of 3 plus years of screen tech research by Sony which resulted in a plastic-backed E-ink screen which was flexible and more durable than most commercially available screens. From time to time Sony has dropped hints about the screen tech, even going so far as to show off a flexible color screen in 2011.
Sony had always conceived of this device as a writing slate for business professionals, and not an ereader. That explains the price and the stylus, and it also explains the format support. The DPT-S1 only supports PDF. It doesn't even support Epub, much less Epub3 like Sony's reading apps.
That's going to radically limit the usefulness of the DPT -S1, IMO
, and it doesn't help that the 2.8GB of storage can hold 3 or 4 average sized PDFs.
Sony has further limited its usefulness by leaving out most apps and features. The DPT -S1 has a web browser but I don't see any mention in Sony's announcement of an email client or other useful apps which might have helped to justify the high price.
But on the plus side this writing slate also has support for an online backup of a user's notes and annotations. There is also mentions of collaboration and conferencing features, but since I am using Google I am not sure how much detail is being translated properly.
