I'm a final year film student in NZ; is it still worth me buying a last gen PB or should I go for a 1.83 MBP? Considering they are the same educational price ($3400), do you think they would have the same lifespan until I have to upgrade again, or the would MBP take the edge? I'd be looking at putting another 1GB of RAM inside both. What is performance of the 1.83 like compared to the 2.0 ($800 more)? Is the performance that much of an increase in apps like Final Cut Pro, over a) the PB and b) 1.83 duo vs 2.0 duo? Cheers.
