Laptops run off batteries a lot of the time - so compromising outright performance - full instruction set - for battery life will be attractive for many laptop users who use it on the go.

I’m no apple fanatic, I’d never get one, but I do see the appeal of those apple laptops.

I’m sure x86 could get closer on the performance to battery tradeoff if they wanted to; but I bet they’d be looking to price up at the apple level for that.
