There's two iPod Nanos, three iPod Touch, and still it's not enough.
You may have found a way to tackle one problem down (family), but what about friends? Are you going to buy iPads for them? I'm 20 years old, always out with friends, it's bound to happen that a friend will ask for my iPad to use. I don't have one yet and I am always asking my friend if I could borrow her iPad for web browsing and games. I never go through her stuff out of respect.
Well, I guess when you get to be 42 you'll learn to say "no" politely to your friends.
