11. The arcade machine is getting there...

    Arcade machines are a thing of the past, you might think. Big, clunky and expensive with a just about as lifelike experience as your old 15" CRT, except for the actual controls. And those only interest people with some sort of nostalgic feeling to the golden arcade days.
