I honestly don't know about the M1's, but I've never liked the price/specs ratio of Intel macbooks. While it's true their build is solid and they look good, they always seemed overpriced to me regarding specs.
And even the build quality... a friend who's an Apple fan used to tell me "they are better quality, they have less problems" yet his macbooks seem to break down at about the same rate as my Dell, HP or Lenovo laptops, so...
I've decided macbooks look good, have good quality screens and the best touchpads. I'm unwilling to pay a premium for that, and I don't even like OS X/macOS...
> I'm afraid that when/if fast ARM alternatives arrive, they will probably cost 80-100 % of what the MacBooks cost.
Possibly! I wouldn't buy them when they are the latest new thing, either.
