No problem! Amazon just released their PC Kindle reader. You install the software to your PC, and it allows you to download and read the hundreds of thousands of boos available through Amazon’s Kindle store. If you travel with a laptop, don’t mind reading on the screen for extended periods of time, and want to save money on the cost of books, it’s a pretty good deal.
You can download the software here.
You can make your first library addition right here. (Molly Fyde and the Parsona Rescue, of course)
