The total carrying cost over ten years is quite low. And my parents have needed much less tech help with a mac. The day to day ease matters and is worth money.
Not sure what it’s like these days, but last time I checked cheap PC laptops were basically disposable; in an old job we had plastic Dell laptops for non-eng roles, and I’d be surprised if the median lifespan was much more than a year. They just broke _all the time_. Possibly things have come on, I suppose; this was a while back.
Not having to manage windows and its bullshit, most likely.
Macs usually require way less maintenance than windows machines. Just install all the upgrades and you're 99% fine.
In my personal experience, my parents (not super tech savvy) always had a windows laptop and never had a specific windows issue due to updates and whatever. If they did, it's more app specific, not necessarily os specific.
In general, I (personally) disagree with the statement that macs require less maintenance than windows or Linux, I use a mac for work, and I have a fair share of app related issues just like I would on a Windows or Linux machine. It's just my opinion.
