If you want to go the DRM route you can share the books with up to 6 other kindles on your amazon account. Also there are books from project gutenberg and other places that you can load onto your kindle. I use mobipocketreader to translate a pdf into a prc file for the kindle - works like a charm. I have well over 100 books that I have replaced from my personal collection and have only had to purchase a couple. The biggest problem for non-kindle owners is the fact that they can't see/touch/play with a device in a store - you have to fork over your money and see what you get. In my case I even bought a second one for my wife. I built a library on an 8 gb sd that we use to load what we need onto our individual kindles. Works great.
