Today I stopped in the only "Apple Store" in my area (CompUSA ) and fooled around on the Macs that were sitting out, when I realized that things such as minimizing (genie effect) and the likes were so much smoother on all of their machines than mine. I have a 15" PB G4 1.5Ghz with 1.5GB RAM and even the Mac Mini 1.25Ghz with 512MB RAM and a 32MB video card was smooth as could be. It's not that my machine is slow, it just doesn't have that "new Mac" smoothness to it. Does anyone know what I'm talking about? Is there anything I can do? EDIT: I even used my identical machine there (with 512MB RAM, by the way) and it was just like the rest of them.
