Sadly, there is no such thing as a universal "smart".

There are a lot of people that one could consider smart that go with windows or mac so as to avoid the sysadmin "hassle" of linux.

with those two os's they can either make an appointment at the "genius bar" (mac) or grab a friend/relative/resident sysadmin at work (windows) and have them look at the problem and come back with a fix while the "smart" person gets on with working on their focused area of interest/knowledge...
