It's an interesting idea, but it doesn't seem likely to get enough marketshare to really matter, and may be too late given that Amazon is now shipping the Kindle Scribe, including the promised integration w/ MS Word, so one can: - work on a document on your laptop/desktop - send it to your Scribe - mark it up - send it back w/ markups There are also a couple of 3rd part e-ink monitors which seem to work well, and a couple of e-ink ebook readers/tablets where it is possible to connect to a computer and use as a second display/graphics tablet (that latter is a killer feature, which I'd give a lot for Amazon to make possible, even if it was only by allowing apps, and putting that in place as an app --- see the "Superdisplay" app for Samsung tablets for an example of how well it could work).
