Does anyone know how I can sync my iPad on another computer? I've installed lots of apps on one computer, but I have some music, movies and more apps on another laptop that I want to sync onto the iPad. I do NOT want to replace everything already on the iPad with the second laptop's library, I want to ADD them to the iPad. Also I don't want to replace the apps already on the iPad, so I can't simply choose to sync apps and not the other stuff. Thanks.
