I think "nerd" has a different meaning, and being more like the genius type. Love to read anything and everything, love to understand, learn, etc. Just generally a borderline genius, and sometimes socially awkward.
I'm not sure of my meanings are "correct" or "accurate" -- but I think they suit the titles very well.
It seems the general population is confused on meanings, and just thinks they are both identical, and like you mentioned above: anyone with a few electronic devices is a geek, and/or nerd.
