People have never bought Apple because of the hardware. They buy it because of the software, the aesthetics, the label, the support (It's easier to find an Apple repair shop than repair shops for any other brand anywhere in the world), and the integration with Apple's services. Comparing spec to spec is missing the point.

Also while this is niche, at the high end (M3 max + 128gb) you end up with a laptop that can literally just do things no Nvidia laptop can do right now due to the gobs of memory directly addressable by the GPU. I'm not saying 99.9% of people are going to take advantage of it, but it is a thing.
