What a clever idea! I saw it and had to share: http://www.favecrafts.com/Crochet/Easy-Keyboard-Duster
I've got to give this project a try right away, as I stare at the little nasties that seem to have gotten into my keyboard.
Isn't it amazing how someone comes up with something so clever, and we just slap ourselves up side the head and say "why couldn't I have thought of that!?" Well, there's no reason why you can't. Often, such ideas come from just doing your normal day-to-day kinds of things, but keeping an open mind to whether a task can be accomplished in a different way or with an aid that will make it easier, faster, better somehow. In fact, here's a fun but enlightening action item for you -- tomorrow, go through your normal routines, but instead of doing them almost unconsciously, think about them and see what variations you come up with. This is often how small businesses that become big ones begin! Good luck!
