I must ask: why would you need one? I can understand it in a car, an airplane, on a missile... but why do you need one on a laptop?

For driving. My new job (probably) will require me to find (probably) obscure addresses in a city (where I've recently moved), the addresses of which I'm totally unaware.

BTW, I have a terrible sense of direction. If I weren't so old I would have been diagnosed as ADD. As it was I was just diagnosed as stupid.
