Obvious use of an idea that I want right now: e-Ink Reference Manuals

For a useful reference manual, you need to be able to quickly get to the topic you’re trying to review or equation you’re trying to look up. This is PERFECT for a touch screen with a slick collapsible interface. Allowing an engineer to have all of his references, with all of his notes in digital form, able to upload/back up would be great.

Maybe the business would be some software to automatically create and populate the structures from scanned books. A book interface in a sense.
