OMG, I'm very depressed as a user who loves the butterfly mechanism. I hate the wobbly feeling that the scissor mechanism produces. Apple didn't need to return to the scissor mechanism, it should have reiterated the design. I'm very disappointed that Apple just gave up & used the safe way of regressing back.
It feels like Apple is losing the spirit of doing things itself, whether other people dislikes it. Apple is more and more becoming a usual company that just does what consumers demands. And I'm sad with that.
