Technology Review has a very interesting set of pictures that show how computer chips have progressed from a single transistor in 1958 (yes, just one) to almost a billion transistors today. The jump from just 4 transistors in 1961 to 5000 transistors in 1974 is impressive.
Wow, we have come a long way. The computing power in my old iPod would have blown away early systems. I can’t wait to see what will be commonplace in 8 more years.
