Wel I can agree to all of what you say, but you are excluding facts like
the harddisks are bigger, rotates at higher speed, the RAM is way bigger,
the CPU is running at higher speed, the graphics adapter is much more power
consuming with the processor and RAM addition. The addition of features like
the USB. Not to mention the added fans in the computer. In my old P75 I have
one fan, in my P4 I have four fans. What have happened is that you get more
computer power for the same electrical power.

Hans
