I think you're confusing microchips with microprocessors.
Microchip: An integrated circuit
Microprocessor: A CPU, i.e. something that can execute stored instructions, has registers, an ALU, and exhibits turing-machine like behavior.
Computers, scanners, printers, network switches/routers, cameras, cell phones, TVs, game systems, heating/cooling system, automobiles, lots of tools and small appliances too
Add to that:
And finally, every single book, DVD, or product that has a deactivated RFID security chip.
If the answers are between 0 and 20, then a better question would be "How many microprocessors are on you personally right now"?
Half the world lives on less than $2.50 a day.
80% lives on less than $10 a day.
