But there are other important factors to consider. I was working on a B2B app where users could see graphs and maps of a construction site in real time. The users were extremely happy how fast we could implement and release change requests and bug fixes. It was an ionic app. As far as I know, performance or lack of OS integration was never a problem. At the end of the day it's about choosing the right tool for the task.
But how much happier would they be with 100/100. Just because you feed your guests chicken and they like it doesn’t mean that they would not like lobster more.
A good MacOS or Windows Dev can move just as fast as a web developer trying to make fake-native apps.
If Android and iOS made it easier to share middleware libraries (C++ is a second class citizen for both), I think there would be a smaller incentive for HTML5 apps.
I get that sometimes it's not feasible to built native apps because you have to do the work twice in the same time and so on, but that is completely irrelevant to how good the product is. Is it good enough? That is a different thing entirely.
I certainly don't believe so.
I think part of the gap is that some folks believe features are everything, and others believe that features are one thing, and quality, support, accessibility and other stuff is just as important, the stuff that in my mind makes good products in general, both in software and hardware, but also in wood-working and clothing and so on.
If features are everything, I can see why cross-platform is what you want, but that is so far away from anything that is Apple.
