Microsoft would beg to disagree with that statement: they bet the farm, in Win8, that one GUI can work for all. They haven't proven it yet, of course.

In any case, I looked at our (daytime job) very large app, and over the past 10 years the UI has been modified, in response to user feedback, to one that will work very well with Lianja's format. So I think your general statement will have to be tested by specific cases, to see whether it holds.
