I've just bought a 40GB Ipod and have a couple of questions. Does the scroll wheel thingy take some getting used to ? I only have to brush it lightly with the tip of my finger and it goes all over the place - it seems to sensitive to me ? I have my main computer set up with all my cds stored in iTunes which comes to about 25GB worth of music. If I plug my iPod into my other computer which has iTunes on but no music, will it transfer everything from the ipod to the computer ? Is it possible to keep in synch with 2 computers ?
