why would you be surprised about something like that? I don't think I've ever looked at someone's desk and been like "damn dogg, why you rollin' all single-screened?"
Because surely at least one of these nerds wants to play WoW on one screen while reading WoW forums on the other -.- (is WoW even the go-to game nowadays??? Should I be making fun of like League of Legends or something more???)
I would probably have dual screens by now if I didn't have a laptop. With both on the same desk I don't really have a reason for dual screens.
