yea, running 22 programs simultaneously (including world of warcraft, photoshop, an emulator, and photobooth - cpu hogs), with 3 terminal dev/null scripts running. i could still go to each program to use it as i normally would, with little to no slowdown.
it is on a macbook 2.0 ghz with 1 gig of ram. i was amazed. sure, the cpu temp was at a solid 85*c, but the computer is amazing. 22 programs, not one froze or crashed.
