Bought my wife a used MacBook Air about 7 years ago. It still works perfectly. I’ve never had a windows product that wasn’t a total piece of shit within 2 years.
Have you ever spent $1500+ on a windows product?
People tend to compare $300 low spec windows laptops to $1500 or $2000 apple apples and it's just dishonest.
If you buy a $1500 Windows laptop it will be going strong for years.
Compare apples-to-apples (ha) and a $1500 Windows machine will demolish a similarly priced Apple in performance and specs and match or exceed reliability. You can find a Win10 machines for around half the price that will have perform as well or better even.
However, something many people don't consider is that brands do make a difference with Windows machines while Apple is a singular, established brand.
One example: the corporation I work for used mid-tier HP's for years (HP ProBook as one model) and in a company of over 3000, we had very few equipment failures. I personally still have one that I've used for the better part of a decade that has never had a hiccup.
They switched contracts to Lenovo branded equipment, similar price/specs and have had nothing but issues. HDD failures, screens going out, docks dying, etc. My personal one just seems sluggish and is prone to overheating while doing very little.
Same specs, similar price, but different brands/components/build quality made a world of difference.
My advice would be to research the brand/model of Windows machine and make sure it is solid. However, if you're not interested in doing that, spend a lot more money and go with a Mac as they are typically pretty reliable.
