I know what you mean. I occasionally get crumbs and who-knows-what jamming up my keys, but so far it's always been quick to resolve by either mashing on the key for a bit or blowing some air into it. I do worry about what they'll be like after a few years of use, however. What if stuff keeps accumulating under there, with no easy way to clean it out?
