The horsepower analogy shows exactly what is wrong with the approach
of trying to compare machines: It doesn't give you *any* information,
except for the fact that the engine, when taken out and attached to a
winch, will be able to lift so many pounds so high in so many minutes.

Frankly, when I buy a boat, I couldn't care less.

When I want to buy a boat, there are zillions of factors that are
of importance: how fast does it go, how much cargo can I put in it,
can it make sharp turns, how far will it go without refuelling, etc.

The horsepower of the engine influences a lot of these things, but
is useless as a measure of them.

In my opinion, the same holds for Mips or Mips/Mhz or whatever measure
you try to invent for comparing computers. Computers are just too versatile
to be catched in a single performance-figure.
