Definitely agree on #1 in terms of bang for buck.
I don't at all agree to #2, but I've used windows for most of my life (even though we do own a Macbook as well), so I'm very biased. What would you say are the benefits of MacOS? I find the UI very clunky, in particular when multitasking, I find handling/switching between a large'ish amount of windows an absolute pain. And of course the fairly limited pool of software available for MacOS.
#3 I can't really judge. Is there any study that would compare Mac durability to that of larger windows laptop manufacturers at comparable price points? From an anecdotal point of view, our Macbook has been running well for ca 5 years now, though to be fair, even a ca. 12 years old windows laptop of mine that originally cost around 400 bucks, still runs absolutely fine (of course on terribly outdated hardware by now). I do know a few stories from friends whose Mac broke realtively quickly after the end of the guarantee period, but wouldn't really generalize here.
