Classical Music on an iPod

I've been avoiding the iPod craze now, successfully, for a few years. The 40GB version was nice, and the 60GB version seems nicer, but I'm looking for a 200GB model. Lately it's been getting tougher to wait since I want my music in one place; all of it. However, I do use iTunes to listen to music. It's a nice front-end to music encoded in formats such as AAC, MP3, etc. I found this article which has some interesting thoughts on using iTunes or an iPod to listen to classical music. It's worth a read, and there's some interesting points you might find useful.
