Laptop stands tend to either be height-adjustable plastic-and-metal folding contraptions, or fixed-height wedges with built-in fans. Both have their uses, but a USB-powered fan (or two) can help cut down on laptop heat, as well as provide a more ergonomic work surface. The $39 Targus Lap Chill Mat is an excellent example of the latter, providing twin fans, a reasonable angle, and a subtle soft-touch design.
Coated in rubbery neoprene, the Chill Matt has a dark gray look that almost disappears under your laptop (most laptop stands are off-white or beige and stand out more). Measuring 12 inches by 15 inches, it's big enough that an 18-inch laptop can sit comfortably on it (although a system this big does spill over the edges by an inch or so on each side). The front edge sits 0.75 inch above your desk, gradually raising to 2.2 inches in the rear, making for a comfortable, if not adjustable, angle for typing.
