"Very happy with this, and upgradable!"5.0 starson by mnovaksan
Pros: I've expanded it to 8 gigs of memory (Apple says only 4 gigs but that's not accurate), and recently installed a hybrid 7200 rpm 500 gig Momentus XT drive. Quiet, fast, plenty of memory and disk space. My main computer.
Cons: Would like a second Firewire port or an eSATA on the back, but not big deal.
