There is a review of the 20 GB model at MacAddict: "Apple's new 20GB iPod improves on almost every feature of the original: hardware, software, earbuds, bundled accessories [...] The earbuds, for example, both sound better and are more comfortable than the original models [...] The remote's clip, however, appears to be designed for women's blouses rather than men's shirts (which button on opposite sides, in case you haven't noticed): If clipped next to a shirt's buttonholes, it's upside down; on a blouse, it's right side up. Go figure. [...] All in all, the new 20GB model solidly reaffirms the iPod's position as the world's best MP3 player. It sounds great, works great, looks great, and includes great accessories."

I decided to look at the web for tips about getting maximum use of my iPod. There are several FAQs of iPod, for example by Apple (pr stuff) and by davyfields.com. Also iPodlounge offers a lot of iPod-related stuff.
