I agree.When Apple switched from Intel to its Apple Silicon processors with lower power consumption and heat dissipation I expected an ultra thin Mac to be announced. So the only remarkable thing is that it took so long.
It was baffling that Apple Silicon Macs with all their power efficiency weighed more than the Intel MacBook Airs.
I have an M3 MacBook Pro and it’s a fat, heavy thing. It’s not even two years old and it looks seriously old-fashioned sitting on a desk.
