Relatively speaking, you can't get much more portable than that. We decided to live with our player on the go, regularly taking it with us during our commute to the office in NY City. The Nomad Jukebox comes with a 6GB hard drive, good for 140 to 150 CD's. There is an ample 8MB memory buffer which eliminates the chance that the music will skip. Despite our attempts to make it skip, the music never wavered.
Songs are uploaded to the unit via a USB connection.
Best of all, both Mac and PC users can load to the player with two exceptions. Right now, Windows NT and Windows 95 users cannot run PlayCenter 2.0, the player's download software. This is a trend that is running in all of the new players coming out. The problem is most corporations have not made the migration to Windows 2000 from NT, nor will they make the move soon. Older Pentium machines, in particular, will require a hard drive upgrade to handle the extra 600MB of space Windows 2000 requires, which means they may never see the upgrade.
