This is completely wrong. For example, a Lenovo X1 Carbon is 2.5 pounds, which is lighter than a MacBook Air at 2.8 pounds. It also offers 32GB of ram, does not have a glued-in battery, does not use glass and the keyboard is much less likely to fail. I am tempted by the M1, but from my experience Apple machines are heavier, fragile, less reliable and less user-serviceable. I also don't understand the aversion to plastics. Aluminium makes MacBooks heavy and can attenuate radio signals.
