I'm toying with the idea of getting another Kindle just to user borrowed books from friends.

1. Give them my "Lending Kindle"

2. Have them register it against their account

3. Download the book(s) I want to borrow

4. Turn off wireless

5. They can deregister my Kindle right away and I take my good old time reading the books I borrowed.

In fact, you don't need to turn off wireless. You can even deregister from the device's Settings menu and it'll keep your downloaded books. (Even if those span multiple accounts!)
