Have you heard of or used Kindle? It's a portable book reader that lets you bring hundreds of books on the go. Amazon.com: Kindle 2: Amazon's New Wireless Reading Device (Latest Generation): Kindle Store Interesting stuff. A bit pricey but I'm sure this technology will get cheaper in the next few years. Personally I like actually holding a book. Also, it would be hard to lend a book to a friend (or sell one) if you used Kindle.
