Much to my surprise, my new iPod was waiting for me when I got home Tuesday night! Turns out they sent it UPS instead of USPS. Yayy!
Only disappointment was that the dock adapter was not included in the box. It was definitely listed in the eBay auction, so I’ve emailed the seller about it.
I charged up the iPod last night, installed the iTunes software and loaded music from my PC.
Today I got a chance to listen to music on the way to work — an accident in the Monitor-Merrimac Tunnel had me sitting in traffic for a half hour. And after I got to work and the morning meeting was over, I pulled it out again and am listening to it as I type.
I’d call the sound (with the default earbuds) pretty good. Not quite as much bass as I like, and a little bit heavy on the treble side, but still quite satisfying. I’m used to very full music, but that’s also because I use larger headphones with my CD player and laptop. At least with the earbuds I can still hear people talk to me. 
Now I just need to get some podcasts, some video, some Mini Golf… and hmm, what else is out there?….
