Yeah, I feel you. I think I know what happened. Some "journalist" took poetic licence interpreting what the developer probably said:
Dev: It took me 5 hours to build and I made $1000.
Reporter: Developer makes $200/hr building iPhone apps.
We've all done this kind of math before (revenue / work time), but I think somewhere the context was lost on this one. Unless somewhere we can find the developer actually saying "I make $200/hr even when I am sleeping."
