I have a kindle fire, Have had it for a little over a year and really like it. It sucked when Amazon shut down all the sites that listed free books, But just look around for pdf and with the right converter you should not have to buy a book unless it is something you really want. It seems that different platforms like different .docs.They should all read pdf's, but it is a pita to read a full page document on a small screen. You are always zooming and scrolling. If I am at home and not on a pc I am on my kindle or asleep.
Hope this helps.
