> I can't share them with friends

Friends? I still don't see a good way of sharing them with my wife without either physically giving her the Kindle or registering her with my Amazon credentials.

That's more than a minor annoyance. I like the device a lot, but mostly because I live in Italy and getting English language books is a Major Hassle and not that cheap, either. With the Kindle, it's both instantaneous, and cheap to boot. If I lived somewhere with a decent used books store, though, I don't think I would have bothered.
