Is It Really Cool?

How do you keep your PS3? In its horizontal position? Or vertical? A lot of people seem to be putting them in the vertical position - mostly because it looks cooler that way. I have to agree. But note, apparently, the PS3 is cooler in its horizontal position - or so someone who used a pair of thermal goggles to look at his PS3 claimed. Check out the following pictures (click on thumbnails for larger images).

Now what can we learn from this? Something that looks cool isn't always cool.
