How does old money separates it from new money? I can't think of anything less nerdy/geeky than an Iphone or Iwhatever - everyone have them now. New money.

Being a consumer of new tech things and download fart apps does not make you a nerd.

Building a computer within MineCraft or doing something inherently difficult which seems like a waste of time to normal new-shiny-money-iPhone-people-without-creative-thinking. That's nerdy.
