I've not used an ipod, but to echo what the other people said, it seems that most people would be happy to call what it does when you press the apparently-off button "off", and not have thought further. I'm always confused by things that don't expect a need for hard-hard.

I'm also irrisistably reminded of Jurassic Park (I may have made this joke before):

- OK, where's the off switch?
- Right here, next to the computer
- CLICK
- OK, where's the reset switch?
- Um. Under the raptor pen.
- *rolleyes* Crap.
