I have a Powerbook - tiBook 800. I primarily use it on my LAP, never on a desk or surface. Anyway, I would like to get a stand that I can put on my lap (a platform of some sort) to diffuse the heat. The unit gets pretty hot on my lap. I have found a bunch of cool stands, but can't find any that recommend lap use. Everything seems designed for desktop use. Anyone have something like this? Recommendations please. Links are appreciated.
