It is even worse if you keep your computor in a bath-tub! When you fill the tub, only the top of the monitor sticks out from water. It's clear that in those conditions it's good to have a warrant for your computor, but it doesn't have to be a long one, because you'll need a help from the service very soon; even more so if you have children! Kids can get very careless when they enjoy the pleasures of the bath, and damage the computor seriously.

Try this: take a large screw-diver, and try forcing a key out of the keyboard. Try another one. A third, a fifth. You shall find that, with a little unavoidable breaking, absolutelly all of them fall out of their places with ease, and break under the pressure. If you try entering some text on a keyboard thus treated, it won't be easy. Even when you put them back in (at least those that stayed whole or in larger pieces), they don't function any more. It is therefore recommended to avoid that kind of actions as much as possible.

Have you ever tried attaching a keyboard to the rear- (or, even better, front-) bumper of a car, with a piece of string, so that it's dragging on the ground; and then drive around town for a couple weeks?
Try.
If you thought nothing will happen to it, you're bound for a surprise.
