Ebook: Running Linux

I got this book after a friend of mine highly recommended. Unfortunately I feel buying a book on Linux makes little sense giving that Linux constantly changes and the book is never up to date. Also there is a ton of material out there on the WEB so unless you just want your bookshelf to look good there really isn't much reason for buying Linux books.

Other then that I think this is still the best written book about Linux. It's easy to read and it doesn't make you fall a sleep after first few pages.
