What take them so long is the question I have.
x86 is probably over powered for what they want to build for most of their devices these days anyways. I mean most of the people do not need all the processing power on their laptop of 14" if a A processor can already run apps on 12".
The major reason to do their own (it will be ARM based like the A processor) would be power consumption. x86 consume too much power, if you make a chip focus on battery life and enough IPs to help accelerate other stuff, it is very likely they can make a thin mac book that last 24 hrs on one charge. Then they can make it really light and portable. App can be compiled for both platform then released on app store, which is a common practice in 2018 but not in 1998.
Macbook is only 2-3" bigger than an iPad pro, so it is totally doable.
