Yeah, that's generally how i shop for books. I only occasionally go into a bookstore with a book already in mind. I just love looking at covers and reading blurbs and flicking to random places in the book and reading a paragraph.On the one hand this sounds awesome, on the other I just hate how this takes away the concept of browsing. I suppose in theory you could flip through different titles on screen, but I love standing at a shelf and then seeing something out of the corner of my eye and going over to that book to check it out.
I can see the usefulness of this at, as has already been mentioned, airports, train stations, etc, but i'm not sure it'll get much past the university 'cutting-edge' appeal.
