Costs too much for me, I'm sticking with my Archos.
You pay too much for pretty with Apple products, I'd love a powerbook, iBook, or iMac but for comparable money I can get one HELL of an AMD based system.
Hell, for the $800 that the iBook (3 year old technology) costs I can get a 2GhZ system with 512MB RAM and a 40GB HD . Or even more.
But back to the topic at hand, I'd go with a Nomad or Archos. For the cost of an iPod you could get an Archos media jukebox and watch movies as well as play music.
