A life? What's that?
The caption for this pic reads “Traders work in the Oil Futures pit at the New York Mercantile Exchange in New York”. The guy’s holding a tablet PC, which means he’s in the oil options pit, not the oil futures pit. (Futures pit traders only need a pad and a pen and a colourful jacket. The guys in the options pit carry those nifty PCs with live market data feeds and pricing software and such.)
We now return you to your regularly scheduled… um, whatever it is that JRE does.
