Gloss on Ebooks, Libraries, and Feelies

I once had a few of my books in Softbook, the first (and now abandoned) e-reader. No reader has yet arrived that has completely satisfied my desire for the book experience. At the same time, as a designer of electronic literature, the ability to link, with sound, color and motion, would be a necessary part of the delivery. The forthcoming Apple iPad might be the platform to do for reading what iTunes did for music (and books on tape, for that matter). If the New York Times can format for it, and all user control (font size, for instance, or orientation), this could be the breakthrough. If not the iPad, then something very like it, I would guess.
