I agree with that. Less heat = less power use, less various hardware failures, longer battery life, better battery endurance. Sealed = no dust buildup, no dirt inside, again less various hardware failures. I'm not bothered by the fan, it rarely comes up. I did install a few games... but they were mostly of the turn based variety and I didn't have time to play them beyond the initial check whether they will start/work. So the efficiency in gaming doesn't bother me the slightest. Actually I wouldn't buy a slate with a discrete GPU.
