When I wrote that, they were talking about many non-improvements and slight adjustments to iOS. I'd say the bikeshedding peaked at the AirPods segment.
I don't think they should be focusing on anything in particular; they know their market better than I do, and it seems plausible that consumers prefer bikeshedding rather than major change. I'm just saying it bores me.
This is the first time in a long time where the Mac segment has been the most interesting thing, and I'd say that they should probably start doing what they're doing to the Mac to iOS. Even if it's not necessarily things I think that are positive, it's exciting.
