Most people by have now accepted that lag and stutter are part of the "New Apple" experience. One can only complain "this much" and move on to better things in life.
Everyone has kinda given up on it as a thing which has the lowest fixing priority at Apple. Different management, different priorities.
It also means that their faith on Apple in "post Steve Jobs era" has greatly diminished.
Oh please. Give me a break. Apple was not perfect under Steve Jobs and never released perfect software ever. It's impossible for any software company to release perfect software. You are just remembering things as if everything was all nice and dandy when Steve Jobs was alive but believe me, the issues were always there.
