One of the things that excited me most about getting an eReader was the idea that I could check out books from the library without having to travel to actually go to the library.
But as it turns out, public libraries' systems for eBook lending were not as idyllic as imagined. Every book available in paper is not necessarily available in electronic form. And though transmitted through the interwebs, you can't just check out a ebook at will. You have to wait for someone else to finish it (and when it's a newer book, you generally have to fend off the bookworm masses).
So the question is, how is your library's eBook collection? Do you actually like using it? If a paper library book and an eBook are both available, would you ever choose the printed page instead?
