You are quite right. A fact most people either don't know, or ignore.
Yet sadly, Apple only cares that it's styling is beautiful. Thermal management is not a priority. It's easier for Apple to simply increase the acceptable temps in their specs, than to design a cool running laptop.
It's always been that way. Not only that, now that they're sealed like an appliance, you just throw it away. Which goes to the next problem that Apple fibs about... "We're a Green Company". Yeah right, that claim was pulled from their advertising, right before the MBPr or whatever the heck we're supposed to call this overpriced retina machine.
I don't expect perfection from Apple, but less hypocrisy would certainly make them more respected from those who pay attention to their BS. If you care about environmental concerns, & the impact it will have on your kids, Apple looks pretty guilty. As such, stop spreading the muck & just shut up about it.
