I think people like books because bookshelves hold them so well. They are decorative. You need something on your wall, but posters are for college kids, so why not some books?<p>I have a shelfful of books. I maybe read one of them every few months or so. But mostly, it is a list of books that I've read that takes up a significant part of my flat. They take up valuable space and collect dust, and are a pain to move, all so I can flip through a book instead of do a Google search. Not very convenient. You could go so far as to say, "pointless".<p>e-books are much better -- when you are done reading them, they become a line on a display that you don't have to dust, find storage for, or pack when you move. And of course, just like real books, you can refer to them years after you've read them. (I guess you can't loan them to people, but for $5, who cares?)<p>And oh yeah, trees. When you buy a book, you kill them.
