I do know that my P4M at idle generates a lot more heat than
my A64 at Idle. CPUID shows that the A64 gets throttled back
to 800 Mhz at idle whereas the P4M gets throttled back to
1100+ Mhz at idle. It appears that you can lower it even
further with CPUID though I'm not game enough to try that.

The fan does sometimes go into "airplane" mode during builds
but is a lot better with the Chili Mat. Perhaps Intel should
ship a Chili Mat with their P4 notebooks (which appear to be
selling better than Pentium M notebooks in the retail outlets).

At WalMart, I saw a Pentium 4 notebook but no Pentium Ms.

wbmw - Perhaps you might want to look at the idle power numbers. No less impressive gap. And for those purchasing the systems, such a disparity in power usage can be a very important factor. Who cares what the end user thinks in the business world, if a purchasing agent is going to buy a slew of the things and the CFO wants power costs minimized?

wmbw:

Let's see, the idle power difference is ~ 73W / system.
The peak power difference is ~ 96W / system. Our typical
client installation is ~20 systems (not counting servers).
So for those clients, the 20 systems equal 1.85 KWhr/day
or roughly $ 0.26 extra per day (assuming peak for 4 hours
and idle for 20 hours, $0.14/KWhr) or ~ $95.00 per year.
Maybe you have a point, not so bad, although the user might
have a nice footwarmer in the winter time. :)

PS. I did not account for the extra cooling needed for the
extra heat.
