You don't know what your talking about. The M series chips absolutely destroy Intel's offerings in the laptop market when it comes to performance.

There battery life performance is far greater than just the ARM benefit. Battery life on macbooks outperformed on intel as well. There software has the benefit of not piling shit on top of shit like windows. As well as excellent firmware, due to the limited hardware they operating system has to support.

You can't get a laptop with such a good screen, weight, build quality and performance for less. It doesn't exist every other manufacturer makes too many compromises.
