I had the joy - or not - of trying to get my iPad to sync with my Macbook Air. It "knows" it is linked to my macbook pro, and to sync with the Air meant first having to transfer all of my purchases to iTunes on the Air; and then I had to manually re-arrange EVERY program in terms of home screens. It was a time-consuming, frustrating process. But at least now I have cleaned up my iPad; I actually dumped almost 6GB of applications that I simply did not need. But I wanted to have the iPad in sync with my personal mac, and not my work mac. Alas, I get to do the same thing with my iPhone, but not today. And since the iPhone does not get video files sent to it, I might not even bother and just sync/backup to iCloud (as I am doing). The problem was by not having the iPad synced to the Air, it would not let me transfer video files.
