So I have a 4G iPod (40GB), and I've been thinking about upgrading, but then I realized all I use it for is music and 40GB is plenty for my music collection which is under 17GB. So I got to thinking, maybe I could buy the iPod Hi-Fi with the money I was going to spend (it was gift money), and then I could also use it with my MBP. What are your experiences with the iPod Hi-Fi? Is it worth $350? What is the sound quality like?
