> It is a given if someone could have made a superior product in the last 15 years, i.e. more repairable laptop with higher build quality, they would have.

Most of the PC competitors of the last 15 years have struggled to even come close to achieving similar build quality.

I'm not sure who this mythical competitor could be, who is supposed to not only match unibody aluminium MacBook build quality, but also solve repairability, and come in with a final product that is cheaper?
