I use an Australian made lapramp to sit my PowerBook on, whether it's on my lap or on my desk.
It costs about $25 and is very well designed and convenient. It keeps the laptop off my lap and lets air circulate around the laptop, thus helping it run cooler. I use it on my desk, because it puts the keyboard on a slant and that makes it easier to use. Go to <http://lapramp.com.au/home.htm> to read more. Regards, Michael Hawkins.
