As the title says, heat dissipation.. The cube looked small and they stated it was "quiet". Most laptop manufacturers just throw you to the wolves and let you fry your hardware or realize you need external cooling. I wonder (hoping, because I do, and want to trust Steam) how they have addressed this issue sufficiently. Looking at the video and thinking of the rules of thermodynamics, I can’t see how you would be able to remove the heat created from a GPU that will preform how they say and stay “quiet”.
