I don't know if it was mentioned before but another difference between AmigaOS and Windows is that in AOS things like windows handling (moving, resizing, also redrawing in most apps) and basic gadgets handling is done by Intuition in its input handlers. In Windows, this is done by the app. That's why you can't move windows of busy apps or change their main windows if any other is opened. This makes the AmigaOS multitasking to feel better.
