Ah man. I am in Africa and don't work for an IT company. So I presume those two factors given the cost of hardware here probably results in many people running on machines with 4GB of RAM. My anecdotal observation is that there is that price of hardware practically doubles from a machine with 4GB or RAM to one with 8GB of RAM. Thereafter increase isn't as jarring but I think it is enough to deter companies from buying 16GB machines.
