It’s about meaningful innovation. 3D Touch for example. That was a meaningful innovation. Apple mishandled it and eliminated it as a feature but it was a legitimate advancement in touch interface design.
Non-meaningful “innovations” are what Apple has been coasting on for years now. “Five more megapixels! .2mm taller! Three bland new colors!” That’s just marketing, not innovation.
It was meaningful? I never understood what a 3d touch is, and how to meaningfully (or even intentionally) do a 3d touch and normal touch. Neither did most other users, by the looks of it.
