Nope, Creative Zen 20GB for me, filled right up. I need a bit more room on it though, don't quite have everything I want from my computer onto it. I use it in my car as my HU has a AUX input, so it's pretty handy. Also, when I'm in the basement drinking and playing pool I can hook it up to the stereo down there and crank it. I never really use it with headphones, even though I got some nice wireless phones around Christmas time.
I don't have it with me so I don't know exactly how much is on it, but I have 23.3GB on the computer, which equates to 5499 songs, and 359:18:41 hours of playing time.
