Query: PC users should beware

I've revised my initial rating after a few days with my iPod. Right now, I dislike the device, but haven't given up on it yet. It worked great until I tried to install it on a second computer. The installation was torture, freezing the computer several times. When it finally looked like I was going to get it installed properly, the battery died. I'm suspicious of advertised battery life claims.Now it doesn't work with the original computer either. When I attempt to sync, it just hangs, flashing the stupid Do Not Disconnect warning for hours.Maybe it's because I'm running Windows 2000 on one machine and XP on the other. Maybe it's because I've got USB 2.0 rather than Firewire. Whatever. iPod is not as PC-friendly as it ought to be.
