Brother Japan just announced a second model in its SV Document Viewer line. The SV-70 has a 9.7" E-ink screen, the same size screen as its predecessor, the SV-100B. Actually, aside from the model number I'd say the 2 models were identical. Based on the spec page, I would guess that the SV-70 will share all of the abilities of the SV-100B.
The SV-100B was released last March only in Japan. From what I can tell the SV-70 is also going to be limited to Japan. That's a shame, because it has it has a number of features that would interest a business customer. It comes with DRM software that allows the end user to lock a document to a specific unit. I don't know of any other ebook reader that has that level of document control.
The SV-70 will be available on 20 February 2010. MSRP wasn't provided.
