I just got a new MBP about 2 weeks ago. I love it, absolutely the best laptop I have ever owned, and the FASTEST computer I do own. But here's my question. I have a '09 Mini with 2.0Ghz C2D running 10.5.8. So the only difference is 400mhz, and the OS. But my MBP just seems significantly faster in ever operation. I'm doubting it has anything to do with the processor speed. So is Snow Leopard really that much more speedy?
