    Just doing my normal multitasking on my 17" it runs fast while with the magsafe plugged in but on battery its pretty slow.

    But then I am transferring a 100gb+ file while using 6 spaces with many apps running.

    Thats what I figured. I just unplugged the magsafe just to drain my battery for the first time and while running 6 spaces with transferring 100gb+ files and running many apps, actually running on battery power I consider it pretty darn fast. :D

    I presume it doesn't underclock it much? Such as 200Mhz? (Glad I bought a 2.66 then :O. )
