I have a second generation Kindle. Can I buy Barnes and Noble eBooks and convert them, or do they absolutely have to be Amazon?

I’ve heard great things about the kindle. But its sold out and i would have to wait 5 months or something just to get it. There are other ebooks like the sony reader. Is there a big difference between the kindle and other ebooks. If not id get the sony reader

I have a Kindle and I’d like to be able to transfer (sell or give) my Kindle ebooks to someone else. Is there any way to do this?

I don’t mean to make an illegal copy for someone, but to transfer my copy of the book to someone else when I’m done, so that they can read it on their Kindle.

Thanks.
