I don't understand the obsession with making a "desktop" as small as humanly possible. The new Mac Pro is not a laptop. It is not a mobile device. I can understand possible desk real estate concerns if the new Mac Pro were larger than the current model, but c'mon folks, this is not a Tetris competition of how to fit a given amount of shapes into the smallest possible volume. Why so small that heat is probably going to be an issue, no matter how cool the new thermal core design is? Heat is always considered in computer design, yet we still ended up with laptops that burned peoples' laps. Naturally, it might all be fine, the proof will be in the pudding. It just seems that a few inches here or there doesn't matter for desk / office real estate, but can make a big difference for heat dissipation.
