That sounds intuitively reasonable, until you look at the current situation where every time you copy paste text between programs that support formatting, you have to cleanse it by pasting and copying through Notepad, or it will do the wrong thing. Note that fixing this would have negative cost: just don't bring any formatting information with copied text.

I used AmigaOS in the late eighties, and found it better than the contemporary Macintosh, though admittedly I don't remember the details well enough to be sure to what extent that was because of the operating system versus the hardware.
