I guess, we are down to expectations management here ;) I do no expect
1.83 GHz dualcore CPU, 3GB of RAM and 160GB of 5400RPM disk to be able
to run at the top performance within 4 lbs package for any protracted
period of time. I am quite happy with it doing -STABLE buildword under
hour-and-a-half and re-encoding DVD movies at ~250fps. Or building
OpenOffice.org under two days ;)

Judging by "2000/Something" you have mentioned below, I suspect not.

Just out of curiosity -- what are you using to visualize this? I was
tempted a few times to put something together, but never really sat down
to do it.

I shall turn off powerd and Cx levels later today and see what I get
than.

There are opinions whether doing C3 on one core (as I do) gains you
anything, but, I believe, there is general consensus about C2. In my
case, it seems to improve both battery life and heat dissipation.

That, likely means 2GHz processor, and AFAICR 64-bit capable to boot.
