Marisa's hack could single-handedly save the laptop-using population thousands of dollars in repair costs:
I stretch a piece of plastic wrap over the keyboard of my laptop (which is in my kitchen) to prevent crumbs, liquids and sticky fingers from damaging it. Every week or so, I just stretch a new piece of plastic wrap. Works like a charm! Mouse and keys work perfectly well when covered by the thin plastic layer, and I can't tell you how many times it has saved my a** [and your keyboard — Ed.].
Do you know HOW many times I've looked up a recipe on my computer while my hands are covered in flour (or peanut butter, or oil, or whatever)? This is sheer brilliance. I know I say that all the time, but seriously, folks — BRILLIANT.
This would work well in a coffee-swilling workplace, too, although co-workers may poke fun at you.
