From the designers whose Cableyoyo device helped make unruly cables a little more manageable, Cool Feet are a compact set of four peg-legs that help make laptops less hot, more ergonomic, and less prone to damage furniture. Attaching via a suction cup (non-iBooks require the included glossy, clear adhesive dots), the silver feet can be easily removed for transport or re-configuration. Three different set-ups—using all four at each corner or only tall or short feet at the rear corners—effortlessly adapt to a variety of situations, including laps. $13 for a set from Cool Feet.
