I have lots of computers. Except for the Unix servers which can typically have their upgrades managed, all of them -- Windows, MacOS, iOS -- all have to be rebooted on a regular basis.

My Sony VAIO with a carbon-fibre shell is way sturdier than my Macbook Air, is faster, has more functionality[*], and is a lot easier to use and has a nicer screen. It is 1" larger and 5oz heavier, whoop-de-do.
Apple products have their place; but that place is not on a pedestal.
