I've got a 8GB Project (Red) 2nd gen iPod Nano. I hate it. It's got a decent GUI and that's about it. I've got a month left on the warranty so, of course, it's starting to break.
I'm totally giving up on iPods. They're fragile and needy and I like my electronics to last more than 11 months. Not to mention that I think the new 3rd gen and touch are the ugliest things that have hit the market in a long time, especially their GUIs. I'm probably going to pick up an 80GB Zune when they drop in November, though I did want to wait until a >20GB flash drive came out.
