A friend wanted me to sign up to the iPod free thing, but I didnt. I really didnt feel like (or have the time to) find 5 people to sign up under me.
There is a neat little program called iPod agent that allows you to do SO much more with your iPod, like one-click synch your songs, transfer your Outlook mail, transfer your Outlook contacts, store weather forecasts and RSS feeds and local movie showtimes from the web and so much more.

I had a crappy Archos 10GB Jukebox back in I think 2002 and boy, that killed Archos name for me. It played music, poorly. It didnt have a high volume control, and it was overall just s***y so I returned it. I would say they have gotten better since then, but I still wouldnt want to get one.
Right now I am on the fence whether to get a 4Gen iPod or the iRiver H120 (a.k.a. iHP-120). I like the remote and recording ability on the H120 (great for lectures) but I REALLY like the iPod because of all the cool things you can do with it now (see iPodAgent).
