By the way, it's not a lack of heat in the Air. The M4 will hit 105°C and start throttling pretty soon in sustained workloads. At any rate, modern Ryzen laptop CPUs have narrowed the gap with Apple Silicon performance-wise. It's mostly battery life that's still lagging behind. It not only requires a mainboard optimized for power use (which is pretty good nowadays on modern laptops), but also very strong OS integration. I am not sure if non-Apple laptops will get that far, because Linux and Windows simply have to target much more hardware.

At any rate, non-Apple laptops have other benefits, like being able to get 64GiB/128GiB memory and large SSDs without breaking the bank.

In the end it's all a trade-off. If you are a sales representative that needs all-day battery life, MacBook is probably the only option. If you are a developer that needs something portable to hop between desks or on the train, but usually have access to a power socket (yay, Dutch/German trains), a few hours of battery is enough and you might prefer to get an insane amount of memory/storage, a built-in cellular modem, and an ethernet port instead.
