Hello, I'm currently thinking about what version of the iPad I should get. Most of my content (movies, TV Shows etc.) is stored locally on my PC so I figured the 16gb version should do. But I plan on using the iPad a lot for magazines (Wired, New Yorker...) and read online that many of those are larger than 500mb per issue which would fill up the iPad pretty fast... So my question is if there is an option in iTunes to backup specific issues of magazines to my Mac, so I only have the latest issue on my iPad but will still be able to access them if I wish to do so? Thank you very much for you help. Please forgive my English as I'm from Germany and it's not my native language.
