if I plug a Mac formatted iPod onto a Windows machine, or vice-versa, will that be a problem? am i gonna have a message that says "u stupid idiot u formatted this iPod on a Mac and u wanna try to plug it onto this Windows? BWAHAHAHAHAHA!!!!" i really dont see why what OS is used would be a problem, but i do see this as a potential problem. my mom just bought an iPod, and before i format it on my Mac id like to know if im gonna have this trouble. if so, i will format it on my windows machine.
