I have the 20Gb ipod and it is fantastic, I also purchased the i-trip with it which transmits onto any radio freq you require on car/house music systems. Nothing better than tuning the radios around the house to the freq and having your choice of music pumped around the whole house, from something the size of a mobile. Likewise in the car it has made my CD-Multichanger redundant. The fact is you put a CD inti your PC and the Itunes software will automatically open and ask if you want it imported into your library, easy as that. It is one of the most user friendly interfaces around today, none of the other MP3 players can match this. I have used the Zen and looked at the Sony and they can match ipod in Gb/hours etc but lack the ease of use.
