I would say: Pre Google Maps era. I find it perfectly intuitive to click and drag most online maps around, but it might have been weird the first time I encountered it.
For example, I still like to scroll down to go down in a web page, and get confused (and frustrated?) when I use the new mac mice which use the touch-screen/map type scrolling. However I'm quite sure that if I was a mac person, I'd get used to it fairly quickly.
