Love my 20 gig...
I love my 20 gig iPod. Easily one of the most important pieces of technology I've ever purchased.
I have about 14 gigs of stuff on my iPod. My entire collection of music, of course. BTW, why is it important to have the entire collection? It's hard to explain until you have it. But, in short, never having to worry about grabbing that CD or the other when you walk out the door is great.
But, my iPod became extremely valuable to me once I rated all of my music in iTunes. iTunes lets you put a rating of 1 to 5 stars. Here's my system: 1 star, soon to be deleted from my system, 2 stars, it's on trial, 3 stars and higher are solid additions to my collection. Then, I create "smart" playlists in iTunes (e.g., a list for all 4+ rated songs, or, even cooler, combining with genre's, all 3+ "indie" songs).
So, now the iPod downloads these playlists, and I have a music list that is autogenerated from my entire collection. I am able to listen to a random sampling (of 400+ songs) of only those songs that are my absolute favorite. It is a somewhat surreal experience listening to that many of my favorites in a row.
Anyway, I'm rambling now. Suffice it to say that I LOVE my iPod. ;-)
