However, this argumentation is not always coherent - for example, equating a lack of foldable devices with a lack of innovation is not an analogy that I would care about (compared to, say, faster refresh e-paper screens for improved professional use, or even just longer battery life). He should give more detailed examples to substantiate his claim of "better hardware, worse software".
From my perspective, Windows, MacOS and Linux (e.g. Ubuntu LTS Desktop) are mostly stagnant or even decaying in end-user appreciable innovation, so singling out iOS appears to be a bit unfair; for instance, X Window supported 16 mouse buttons in 1984, and what's new in Wayland? (And don't get me started about menus called "..." on any platform - one used to find things much more easily in the past before bloat took over.)
