Ok, im not that tech savvy, and need a little help. I bought my daughter an ipod touch and my son an ipod nano for xmas. My question is, can you only load songs, games, and video's onto them from itune's? Also, if my daughter buys a song from itune's, and puts it on her ipod can my son put the same song on his as well and vice versa? Or if you buy a song is it only good for one ipod? I hope someone understands what im trying to say and can help.
