I've been thinking about replacing the hard drive and battery in mine for the past few years. The wheel-based iPods really did have the best UI for music in any device I've ever owned. If you're familiar with it, you can navigate with extraordinary ease.

Years ago, I replaced the 20GB drive in mine with a 30GB drive, because I was having issues. It was pretty easy with my 4th-gen iPod. Turns out that the issues were actually in the USB interface, not the drive itself. So I struggled to get the drive re-filled, and haven't changed the data on it in...probably 7 or 8 years.
