yeah i get it, i was just trying to logically dismiss the "battery + heat = bad" claim.I might add it makes no difference which power source is used the CPU's cooling has no bearing here.
The only thing Apple could do is cripple the CPU to four cores when on battery then you plug your system into a dock system which adds the needed cooling (liquid) to an external radiator system to then allow the system to go full bore! Gee, thats been done and it failed!
apple just failed here because they were expecting more efficient chips from intel, and user base have been pressuring for a good cpu update. (which is reasonable, because quad has been in macbook pro since 2011)
