My Zen Micro is 6gb. Thing is great, plays wma and mp3 format. I like it becuase its small as as hell, and you can allocate a portion of the disk space for regular storage. Like say I want to keep 256 mb set aside for storage, I can go to a friends and copy photos, music, or any kind of files to the drive as well. It also has an fm radio and a recorder which you can record the radio, or from the internal mic. Ive seen all ratings equal to the ipod in magazines. You can also get it in a shitload of colors. It's also on sale everywhere for like $160.
