I love mine too as well! It's 8gb.. and I got it at a good price, $140.. it's only two years old, in like-new condition, and STILL under warranty. The reason I did this was that I wanted to have a smaller one to start off with, and I keep hearing rumors that eventually there will be a camera ON the new Ipod Touch coming out this spring/summer.. but who knows?
I take mine with me everywhere I go. It BEATS having to carry a laptop with me while I can just go on the Touch and surf the web, e-mail, etc. MAIN reason why I got it was its Wi-Fi capabilities.
