If they bought a 2.0GHz CPU laptop, ondemand just will going to scale
to 2.0 as were necessary, if I'm opening openoffice or something
similar, are u sure that ondemand will switch to 2.0 or 1.6 ? , why
the user need to experience a slower machine if he's connected to AC ?

Ondemand is a good solution for a lot of situations, here we're
talking about the 'Laptop connected to AC' case..

good question, but is not necessary to spent some time to get numbers
to see that our machines are a little slower with ondemand.

It doesn't make sence to me to set a slower CPU when the laptop is
plugged, ondemand is very helpful but my point is performance.

I'm just proposing to change the AC policy from ondemand to
performance. Plug your laptop to AC and do some test using ondemand
v/s performance, which one is more faster ?, which one gives the best
user experience ?.
