Ive taken a gap in the apple product ownership. It used to be in the old days when I had the ipod touch, that you needed to backup a soft copy for yourself because you cant redownload old movies. Apps I think you can redownload? How about nowadays? Can you redownload movies, apps and songs as many times as you want on your device in case you reinstall the PC or do you need to do a backup of all the music and movies?
