What keeps me in the Appleverse is the hardware, and the software that Just Works with the hardware (I find that "Just Works" has been rapidly eroding in general, but naturally it still handles the hardware well). The alternatives are Linux on much worse hardware, or the non-starter that is Windows on anything whatsoever.

I'm told ThinkPads are getting to parity and have primo Linux support, but barring accident, my M3 MBP will probably last me a decade. Another reason I prefer Apple hardware.
