Yes, It works better than a G4 but it is heavy and HUGE. I had great expectations but am sorely disappointed. I am now using one at work and the 10.3.3 finder is still a dirty dog. Slow and clunky. Problems with sleep and shutdown. Crashes with Quark. And the font issues are disgusting!Photoshop still runs 5x faster on my Dell M60 Laptop workstation with 2 gigs of ram and 128 meg video card.
