I wish I had a stat on how many people are "tech heads". Of course, most of us who come to this forum are, but we are a minority. Many of the ordinary people who are using iPhones (and now Android), know little about tweaking their phone. They just want it to work and be able to do lots of things to make their lives easier. But again, I don't have numbers to prove one way or the other, just interested in the theory.
