I am a PC user and I'm planning to switch with a iBook or PB this summer.. I already have an iPod 10gb Windows but I'll sell it and buy a new rel.2 iPod.. After I'll buy my portable mac, I'll go on using PC at home, so which version of iPod would you recommend? does the mac version of new iPods work with PCs without macopener kind of programs? does Windows iPods need another additional program to connect to a mac? which one do you think should I purchase?
