Question - I'm going to buy the iPad 3 when it comes out, but I plan on keeping my iPad 2 as well. I'm still kind of new to Apple so I'm not sure- will I have to pay for all of my apps again or will it let me keep them on both devices? I thought about leaving it at my girlfriend's house, so is there a way to just make her an apple ID so she can download her own apps, but at the same time leave the ones I've already downloaded on there?
