I have a Creative Zen V plus 4GB.
Configurable (and intelligently designed) OS (yay KH wallpaper), supports pictures, audio and video, as well as recording. Nice and small, but NOT paper thin, ergo durable. And one of the best features of all, it's Drag'n'Drop. It comes with bloatware, but the bloatware is entirely optional. You don't need to put up with any bullshit if you don't want to. Plug it in, drag your crap into the right folder, and there you go. Musix.
Quite like it, even though it only holds 4 GB (another 4 or 6 would be more than enough though probably).
