The only thing I dislike about ebooks is that I can't throw them out the window after a final. Having said that, I should note that there are also a lot of Digital Audio recording series for sale online. You can buy recordings of Bar Exam Prep courses and stuff, and it costs a lot less than an actual class. The only real difference is that you personally cannot ask questions, but I don't think that's too bad.
Ebooks are good, audio recordings too, same with legal research websites. Things just get better and better... except politics, money, power, and influence... that generally stays the same.
