Hi all, I am going to be getting an iMac soon, already have a MacBook and also a PC. I use iTunes on all of them - but would like to keep my iTunes library up to date on multiple computers. Smith Micro's Tune Ranger is (In reality) crap. So does anyone know of any software or hardware that'll allow me to do this? Also, I know you can share you music over a network in iTunes, but I want to be able to have up-to-date content on my MacBook when traveling etc.
