It says that the geekbench used on the Vaio is 32 bit. I can only assume that is the reason for the difference. Even though the Mac geekbench also says 32 bit, I don't think that's right since it would've shipped with Snow Leopard which is 64 bit.
The 64 bit test on the Vaio Z is the same as the MBP as shown here:

Any objective proof of your claim?
This statement is ludicrous. How can more ram not make a difference? More ram = more programs opened for multitasking and more memory for programs to use.
Proof that the Vaio Z is clocked low? You don't even know what the MBP is clocked at so why even bring this up? Apple are notorious for underclocking the GPU. People in glass houses and all that.
Again, do you have any proof to back up your claims or are you just spouting nonsense? The Z employs carbon fiber and aluminum. It's definitely not a poorly designed laptop made from cheap plastic.
Take a look at all of these QA tests Sony does on the Z:

Care to try that drop test on your MBP for us to see? Or the pressure test? Impact test?
You mean the operating system that can't play Blu-ray, HD Flash without choking, high bitrate HD without stuttering (unless using VLC, which says a lot about Apple's programmers and how junky Quicktime is), has a joke of a file manager called Finder, et al? I won't even mention lack of gaming.
Want to know what's even funnier? Apple won't support hardware acceleration for h.264 on my early '08 MBP but Win 7 will. Nice to know that Apple dropped support that quick for a 2 year old computer.
The Z can run 6 hours at max brightness. And if you run out of juice you can actually pop in a new battery. Run out of juice on the MBP and tough luck if you don't have an outlet.
