You want to bet?
Sure, go ahead and count up your supercomputers, and I'll try to estimate
how many PS2's etc there are in the world.
That's by CPU cycles - I think you'll lose. Big.
Do the same by economic factors, and I suspect you're on slippery ground

Do the same by number of users, and I _know_ you're done for.
I know, it's nice and comfy up in your ivory tower. Go on, ignore the rest
of the world..
