I'm considering one for use as a portfolio, and for reading while traveling (if it turns out that it's possible to charge it with solar power, it might even go on the list of backpacking luxury items, to serve as a book, journal, and possibly entertainment (games) device in case of being tent-bound during inclement weather). But my main intended use would definitely be as a portfolio of my photography. It wouldn't hold a candle to the image quality of my print portfolio, but it would be easier to update it regularly, and to have custom sets for showing different prospective clients. So even though it's mostly a nifty toy, it does have some potential use. We'll see how well that pans out, I suppose. I think there are already some apps floating around or in the works that enable tethered photography for studio use, which could be useful also, although I don't do much studio work.
