This brings home how much comples technology is available nowadays for only a few pence after auto assembly by pick and place machines, as opposed to the expensivemechanical assembly needed for a roller ball mouse.

Presumably a DSP in addition to a CCD device. possibly more computing power that went to the Moon with the Apollo landings?
