I have to agree with Tony, I like real books too. There's nothing like printed paper that you can take and read anywhere. The other thing I like about the book publishing process is that generally, at least initially for new authors, abut also to some degree in a continuing way, there is some level of independent review for accuracy in "textbooks" and the like. Simply because the publisher won't want negative reviews of the books to come back and bite them. This is not true of self published work on the internet, where I am always a little wary of the quality/reliability of the content. You only have to look at a subject that you have a decent amount of knowledge about on Wikipedia to see just how poor some content can be.
