As much as I love my Kindle - did you know you can download Kindle for PC (from Amazon)? It's free, and only takes a couple of minutes. Obviously you have to read off a computer screen, which is nowhere near as good as the proper Kindle screen, but you can road test books before you buy. Most of them have at least the first chapter available as a free sample. I've downloaded loads, but only buy the ones that have me hooked.
