My six-year-old son recently got an iPod Touch. I put it in a protective case and put a protective foil on its display but I was pleasantly surprised how careful he is.
His older brother (11) and sister (9) both have one, too, and they're acting very responsibly, too.
All three of them had to pay a substantial amount of the price themselves, though, so that might have helped in making sure they're being careful. :-)
