The Macs all throttle with heavy workload that raises the temps no matter what you do. The efficiency (and battery life) comes from the hardware being configured to do certain things very efficiently, like video decoding.

Compute is compute, Apple didn't circumvent physics. It just managed to take chunks of that compute that represents the most average use case, and make it more efficient, in the same way that ASIC mine bitcoins more efficiently than GPUS

As for keyboard, it still sucks. Impossible to clean without taking the thing apart, so if you get any dirt under the keys, its gonna be there for quite some time.
