It all seems too good to be true, memory and ssd upgrades aside, the M1 devices seem to be fantastic value for money. Also waiting for a 16" M1, decided to order a mini in the meantime.
It definitely is. I'm daily driving a Macbook Air, something which I never thought I'd say. Even beyond the CPU crunching performance, I'm not sure what part of it is causing this, but it's just so much smoother for a variety of misc things. I suspect either better coupling with the integrated GPU or the unified memory.
But many little things, like the smoothness of the OS, or the way that the screen wakes from sleep instantly are just superior to my much more expensive, and power hungry desktop. Of course, my desktop can still cream it in a GPU workload but for programming, it's amazing.
I recently moved back to Arch Linux after spending the last few years using a hackintosh full time. There shouldn't be any reason to need to keep installing an OS; if you're competent, you should be able to correct any issues.
For many peoples workflows including my own, Windows would pose a far greater headache to get to a productive state. macOS works great, up to the point where you want to enjoy freedom to use your computer as you see fit, certainly less hassle for development (in general) than Windows though imo :)
Next to the trashcan on the top right of the network tab, there's a button, which when hovered, "ignores the resource cache when loading resources." I think this what you're referencing.
I guess the only solution is for us all to switch to Chrome, everything works fine that way.
