I bought my classic 15 2.5 for full (well , student) price right around July lol so I'm a bit upset, but I heard the firewire chipset in the unibodies was lame compared to the previous gens. That said, I don't like the unibodies glass screen, and the end to end finish with no edges makes it impossible to use a 3m privacy filter which is a must for idiots on planes, trains , and buses who like to comment on my work. I also have a few fw400 devices and the 20 inch apple cinema display so i'm glad I don't have to shell out for an adapter.
