Yes, it's what most people want. As a developer, I do not miss the days of trying to drive people to my website to find my app. If you were lucky you could get a mention on a well-known website or one of the many download aggregators, but it was hit and miss. The Mac had some very good ones, but with Windows, not one was big enough to be worth your time. It was a nightmare. Getting noticed on the app store is non-trivial, but at least your product is already in the place where users are going to find stuff. It's one less thing to have to worry about.

As a user, I don't miss having to search the general web to find something for my computer, only to be misled by poor results in the search engine, malware download sites, software that would be the perfect solution but doesn't run on my OS, ads everywhere, etc. Now I have one place to go and everything on it works with my system. Sure it's not perfect, and discovery could be improved, but there's no malware that I've ever run into, and everything I actually need is there.

Also, it's a false dichotomy between PC OSes and iOS. Both macOS and Windows have app stores that their users use.
