Crumb Collector for Laptops and Keyboards
Have you ever tried to clean out all the crumbs from under your computer keyboard? It's disgusting, yes - but nearly anyone I know does eat at the computer now and then.
So why don't keyboards come with crumb collectors? It's standard with toasters (so it's pretty much tested technology) - I'm sure it can't be too hard to adapt this to slightly more sophisticated devices.
