Mike L mentioned in a few posts earlier, if you don't have anything else to read. I've borrowed my college kindle(K2) quite often (too bad they don't allow you to take it for more than a week, else I'd have it right now
)and I think its one of the big draws of the kindle. I can already imagine myself in plenty of situations where it would be a definitely better way to pass time if you're tired of reading books on it
