The log pillow is a ridiculous concept, and at $80 it seems like a perfect way to seperate a few suckers from their cash. It's either blocking intakes or exhausts (not to mention various ports) and generally insulating the laptop, not to mention increased dust and ESD risk. One would imagine that tech-bloggers would be aware of such things.
