Ironically, for many of us we can't do our jobs as non-admin, because admin functions of various kinds are required throughout the day (i.e. installing programs, compiling stuff, dropping temp tables, etc.)  I think you are asking the wrong group of people.  There are a fair number of "regular users", one example group is (ironically) called "administrative assistants", who don't really need those other functions and are usually logged in as "non-admin" users.  That has been the case at most of the br/click and mortar businesses I have seen.  Software companies are not that way, though.
