Even with the latest in thermal-energy-dispersing heat sinks and cooling fans, today's laptops still manage to get pretty hot even after just minutes of use in some cases, hot enough to literally burn your lap if you're not careful. Our recommendation: don't even think about putting your notebook directly on your thighs without a cooling pad. The curved, plastic Logitech N100 laptop pad comes with ample air vents plus a built-in cooling fan powered by a USB cable attached to your laptop. (Logitech claims the cooling fan will shave only a few minutes off your notebook's battery life.) The laptop-sized N100 might be a bit cumbersome to carry around with your notebook, but it's better than having to explain yourself in the emergency room.
