Well, whatever you do, JEMelby, make sure you hang around!
I think there is an excellent market for the device you're describing (it's come up before around here, on occasion) -- Academia, the legal profession, most office environments, and anyone else who deals with large quantities of ...
stuff that they have to sift through and interact with. I'd like to have one myself, I just wouldn't likely use it for reading -- it would pretty much have to have an A4/letter-sized display, and that'd be too cumbersome for leisure reading in my ... er, book.
