Lap desk for heated MBP?
I have only recently bought a 15" 2.4GHz MBP. Being a lazy bum, I have the habit of using my laptops on my lap or bed. However, I have a feeling that my new MBP (not even a month old!) tends to heat up a lot when I use it on my lap or lying down on the bed. Will you advice to buy a "lap desk" or sth that will help in cooling my mbp? I do not usually prefer using my notebook on a desk as a desktop and would therefore be willing to spend a little more in order to use it as a real laptop. What is the solution to this? Which are the better lap desks? Or is using a pillow or notebook in between the lap and the base of MBP is fine? Please advice...
