Okay, I'm sure EVERYONE but ME knows the answer to this but I'm gonna ask anyway... I have an iMac. I am getting an Air. I have an iPad and iPhone. Can I open up my new Air, start up iTunes, copy all my apps and some of the music (so I don't take up all my SSD) and have it work? Or will iTunes say that the apps were purchased on a different Mac or that the iPhone is synched with a different library?
