That's what I have for my workout/running MP3 player. It's awesome, and the battery lasts for like 25 hours, or something rediculous. A little different to navigate, but it's 4GB. I haven't really messed around with making playlists on it, but you can. It's also drag-n-drop, sounds great, and is under $100. I think you can get them from Best Buy for about 50 ish.
My roomate has a 120GB zune, and it's really nice, in my opinion. The sound is way better than anything iTunes and the iPod dish out. I have a Mac and an iPod, so you can't say that I'm hating on apple. iPod used to be the better player, but now Zune/Creative players, have the quality. Only thing I can give Apple here, is that my iPod will not break. It has dents in the metal backing, and still runs with no problems.
