We're always eager to turn to our cheery bunkmates at Lifehacker for helpful hints, and here's a good example that we were wondering why we hadn't thought of before: Use the sticky side of a Post-it note to pick up crumbs and such that gets stuck between the keys of your assorted gadgetry.

Crumbs, dust, and goo can build up in the keyboard or on your wireless device, and if you don't have a microfiber cloth or mini-vac handy, those Post-it notes you're carrying around in your briefcase can multitask at home or on the road. Slide the sticky side in between those keys and funk-be-gone. You do carry around Post-it notes, don't you? Doesn't everyone? – Charlie White
