I'm the proud owner of a Ipod 40Gb and a Karma. The Karma beats the Ipod all the way. It's FAR FAR more superiour in both sound, technical features, ease of use and last but not least batterylife.

I travel alot on planes, and use the Karma to help me focus on work in the sometime noisy planeenviroment. I can strongly recommend the karma over the Ipod.

Cheers
