if u have windows its probably better. mac osx an 9.2 make duplicate non playable files (ie._filename.mp3) and the player stops after each track. so unless u manually remove the fake file it will not go from song a to song b and so on. also usb isnt 2.0 on older macs. the newer macs have usb 2.0 and if u have a good ds store remover program and usb 2.0 its worth the money. otherwise pc speed would be good
