Just Mobile’s Cooling Bar addresses two of the MacBook Pro’s problem areas--its tendency to get very hot and the less-than-ideal ergonomics of its built-in keyboard. A hefty metal rod with a flat edge on the bottom and nonslip rings on both sides, the Cooling Bar rests under the back edge of your MacBook on a flat work surface. The bar does not physically attach to the ’Book, relying on the nonslip strip on its flat bottom to keep your laptop from rolling backward as you type and use the touchpad. It’s a well-thought-out design--though it would probably be more stable if the flat part of the bar was a few millimeters wider. A slot on one end of the bar is meant for the ’Book’s power cord--a nice touch. All would be perfect if the cord slot was a smidge deeper, however.

At 8.8 ounces, the bar is too chunky to carry everywhere, but its heft does help keep it from sliding around on your desk.
