I think that the rollable paper displays will solve any contrast problems, and allow for low power consuption. The thing I like the least about real books is that they're a little bulky. Sometimes I like to lie on my back while reading, but it's hard to hold the book up after a while. Sometimes I'll lie on my side, but then I have to change positions every other page. I think it's hard to really get comfortable while reading, and ebooks should solve that problem.
