[OtterBooks]

I don't think the device category was a good fit for Sony. Success here requires more than pumping out a compatible device (which by most accounts they did very well). You need a close connection to, and understanding of the industry and consumer culture of books in order to play on that field (and even then, it's been a near-hopeless game with Amazon playing). Those things are foreign to Sony, imo, and I suspect they are relieved to wash their hands of it and get back to making products that distract people from books. edit: even if it's just a partial exit from the market.
