Comment Re:more than 20 is too many? (Score 1) 559
Should I count the old NES I have sitting around? Its CPU is probably less powerful than the microcontroller in my dishwasher. I know for certain that it's less powerful than many of the control chips in my hard drive. The ICs on a hard drive alone have enough power and RAM to run a sophisticated, modern OS (depending on how general-purpose the ICs are).
I could probably point out more than 20 microprocessors within 3 feet of where I'm sitting without too much flexibility in the definition.
