There's a big difference between your two scenarios. At the time the iPhone came out, only a very tiny fraction of people had ever owned (or even used) a smartphone. The iPhone's success came because it was able to grow the market, convincing feature-phone users to upgrade to a smartphone. I don't see the same thing happening with nginx. I don't see anyone saying, "Gee wiz, I didn't want to be a sysadmin, but now that I've seen nginx's easy config file syntax, I want to be a sysadmin now."
