Transistors are go! In the '50s, transistor production was in the millions. In 2003, it hit a quintillion, or a trillion million. Prices have gone the opposite direction; some people estimate that a transistor now costs about the same as one printed newspaper character. And transistors have gone way beyond diminutive. Intel says some are so small that about 200 million could fit on the head of a pin.
