You literally laid out your UI in a WYSIWYG, drag and dropped connections to your code, and had something working on day one.
It was even easier than the web, because what you were laying out were full components with code and UI and behavior. The web still hasn’t caught up with that fully.
When I see comments like these, I better understand why old timers shake their fist at the youngsters reinventing the wheel badly because they don’t understand what came before.
