Worldperks - I take it you refer to the Creative Labs version of the iPOD? Those things are cool - 2 batteries and you can listen to the it for 22 hours and it's tiny. I am still running off my (now ancient) 6GB 4 hour battery Digital Jukebox which is the size of a CD
walkman with 1500 songs on it. The number of songs you can get on the hard drive depends on the bit rate at which you rip the track - anything less than 128 is murder on the ears but 320 produces real quality ripping.
The answer to the question is - any of my 1500 tracks that I fancy - never will I be at the mercy of the airline's IFE.
