Here’s a great idea that DeWalt should get their asses on: A handheld 18-volt air gun that can be used to dust, airbrush, or fill up basketballs or bike tires. I’d get one if it meant less time on the bike pump, and it could start a new genre of krylon-free, duel-wielding graf artists. Found this cool gem of a fantasy gadget over at the newly designed and even sexier Core77 website. [Core77]
