No, but the recent spate of apps that take user experience when accessing third party content very seriously shows how utterly painful most of the normal web is. I think with first-party content providers it's also that if they're getting paid, they at the very least cut the ads down from eye-gouge to simply irritating, which helps as well.

I think maybe the point is that while there's nothing technically special about the platform, at the high end its developers are in a league of their own when it comes to UI. This is of course a distilled version of the entire Apple developer culture, which has always taken this stuff more seriously than Windows and certainly *nix.
