One thing you have to learn about technology is that no matter when you buy something, whether right after it comes out or a little later. It is going to be replaced by something, faster, lighter and better within a short matter of time and then you will want to upgrade again. My advice, buy what you want when you want it. Something newer comes out, so what? Keep what you have until you no longer have use for it and then upgrade. The new Core 2 Quadro processors for the MBPs coming out actually didn't have that much of a difference in their benchmarks compared to the Core 2 Duo. So why rush out and get rid of your Core 2 Duo? I know you want the latest and greatest but in reality, they both do the same thing.
