But the Mac does have Back Doors telling Apple what you're up to:

I do agree on the "no crapware", elegant, simple, integration, and literally everything else. But Apple does have Backdoors, just not to the government.
Adding to other comments, even though flagship Android phones and Windows laptops are sold for the same price as Apple today, historically that was not the case. Apple was always selling premium devices at a price much higher, and that premium persona of the brand sticks even today.
Apple also strives to make "devices that just work". So when it doesn't, people point it out. Other companies don't advertise their devices that way...people know that the Galaxy Fold is an experimental device, and treat it that way.
At 300, you’re limited to the SE. It misses out on some health features.
I’d actually suggest looking into some diabetes related solutions (plenty of small devices that do that). Apple Watch is great at heart rate, and similar stuff; but not so much for blood sugar (idk if it does that even).
