I don't get the whole kindle thing. I used a friend's and saw no benefit over paper books. The benefits I hear are things like, "It is easier than carrying around 20 books." Who the hell carries around 20 books with them? I don't need to be reading 20 books at once.
I think it is a gimmick and a percentage of those that sing its praises are trying to justify to themselves the high cost they paid for it.
