I own a MacBook Air and I agree with almost all of this except the hardware part. I like Chiclet/flat keyboards more than mechanical ones. The battery is good. The weight and size is what every laptop should aspire to be. The only thing I found difficult (and still do) is the layout swapping fn and ctrl keys.

The software on the other hand... <rant> is surprisingly terrible for something that is praised as "just works".

Why is the close button there if it serves the same purpose as minimizing? If it's meant for hiding, why is it a red x?

Why are windows so difficult to organize? If you're not a tiling WM user, then good luck finding a workflow that works. Why is there no proper way to make project separated workspaces similar to Windows desktops?

Why does pressing "return" rename a file? Why do keyboard shortcuts just refuse to work sometimes?

Why is the preferences app so broken? What is the point of search if it doesn't search anything at all?

Why are updates so large? Why does only macOS take 35 GB out of my 256 GB?

TouchID is better than any other login type on any other system. Who uses a password that often on a computer anymore?

The red x doesn't quit apps, it closes windows. CMD-Q quits apps. There are certainly times when you want an app to be running, but with no open documents. This is basic PC stuff, not sure why you don't seem to understand it. Not every app running even has to have a window, so your paradigm doesn't make sense.
