It's years of fantastic painless experience and even now it's relatively good. Before using these laptops I never knew what it meant to just slam the lid, then hours or sometimes days later open it and start from where you began, instantly.

The privacy. The comfort of having two devices (phone and computer) to be in sync in a private and safe manner. Excellent app ecosystem. Timely and long term updates, upgrades, and support.

But as the parent commenter says I am at my wit's end as well, for the first time since I started using Macs a decade ago - crappy recent OSX and iOS releases, iPhones getting bigger and bigger, being trapped in a data/communication silo etc.

So why am I still here? Because there's nowhere else that's better.
