Laptops for Warm Climates?

macrostiff asks: "Where might one locate a product comparison for laptops and notebooks that includes environmental specifications? Why do I want this? Well, I'm on my second notebook that will not work outside of a climate controlled environment. In the real world, one often encounters temperatures above 35 degrees celcius. I've been through two notebooks for which this was the specified operational limit, which was not published, and the manufacturer or dealer led me astray until there were problems. In particular, I am looking for a notebook with 900MHz or faster CPU (fast enough to play DVD's) which will work under full CPU utilization at 40 degrees celcius (104F) and 90% relative humidity. While a bit extreme at the limit, 35-38 degrees and 80% relative humidity is not uncommon for those of us who work in areas with no air conditioning. Oh yes, it must run Linux!"
