Hi Me and my girlfriend both have iPads and now she's going away over the weekend so she wants some movies on her. I have a Mac with handbrake to convert and all but the thing I've heard is that if you hook your i-device to a Mac and iTunes, you can't do it with another without erasing your data. Since she's planning on getting a Macbook Air, she doesn't want her device too be linked to my computer. Is it true and is there some way to get around it? Or are you allowed to link it to, say, a couple of computers? Thanks in advance!
