All I want is a little intellegence in the hardware so that the well defined things the computer has to do over, and over, and over, and over, are quicker. There are some really obvious things which those millions of transisters could be doing. >complete out of order.

This means that it's much more difficult to create a program which is both small and fast. (It doesn't help that many apps developers have no sense of craft.) -- Jim Williams.
