It pops up with exactly as much frequency as a normal user account in most Posix-like systems would require "su" of one form or another. For exactly the same reasons. It's just expected behavior for those systems, but completely unacceptable for Windows.

It was the collision of Microsoft trying to limit "run as admin" and Windows developers taking users running as admin for granted for too long. There had to be a period of pain as "if it ain't broken don't fix it" developers got around to not asking for unnecessary permissions.

These days you mostly see the prompt when you're installing or updating an app, which makes a lot of sense.

What I mean is, this is Microsoft's fault so far as users got in the habit of running in admin in the first place, but I doubt you would've been able to do better given where Microsoft was with its software ecosystem going into Vista.
