Not fast compared to what: the newest model, your friend's computer, the way it performed when you first got it? There are many threads about improving sluggish machines, if that is what you mean.
Is slow compared with a Pentium 4 HT 3.2Ghz 1 GB ram, i've been working with windows and pc for more than 10 years, i've purchased a mac to work faster, but it seems equal than my old processor and windows.-
I've tested the system with photoshop CS3 and works nice, but i don't see a big difference,
when i've purchased this mac, it was for some reson using a bad installation, and the mouse wasn't with a smooth scroll and motion.- Now i've installed a clean version, the speed seems to be fine, but is not somethign "IMPRESIVE", is working just like my old PC
