If a review is looking at hardware, and MacBooks are out there, shouldn’t they be included for the benefit of people who are actually trying to understand their purchase options?
Sit a person who's only ever used Windows their whole life in front of a Mac and ask them to find and launch a certain application. Once they realize there's no Start button they'll probably be completely lost.
But, it sounds like you and I land on two different sides of this. Your point seems to be that other OS machines shouldn’t be included because of that significant entry barrier, and my point is that if the review is being presented as a comparison of the best hardware options, then it’s not accurate to eliminate MacOS machines on the basis of software. I’d sooner see reviews either (a) compare exclusively same-OS machines and say so, or (b) disclaim that users might face that bigger entry barrier, but show the comparison and leave the decision of whether learning a new OS would be worth it to the reader
