I remember visiting the brother of my friend quite a few years ago, he had a big iMac in his living room and asked me to put on some music. So I hopped over and was dumbfounded on how to right click. So I asked my friend and he basically said 'there is no right click' (note, both of them were mac users, I wasn't), and then I said surely there must be a right click!? Then he asked his brother and he was like 'don't really know, there's a key combination or something you can press I think'.

Anyway I put on the music and thought for years macs had no right click and never bothered to investigate further. I never had Apple money as a teenager and never used Macs, and given both of them had for years I thought they must've known. I'd been in the back of my mind ever since, hesistant to even consider switching to OS X. Until my early 20s when I needed a mac for work, looked into it and right clicked on my mac ever since.

I wouldn't dare put a number on the amount of users they missed out on, but I'd likely have switched a few years earlier. That, the price positioning and the minor hassle around office as a student were the three biggest things preventing it. The first ended up being totally false, the other two became less important as I stopped being a student and started a career.
