The Sony also has 1GB of Discrete graphics through its external gpu, the Power Media Dock, just plug it in to the laptop and then it is running on discrete graphics. The Sony still has the smaller form factor...it's still smaller and lighter than the rMPB and packs much of the same power.
Apple definitely has great, if not the greatest customer service no denying that. Hardware wise apple does make great stuff, but these LG screens in the MBA seem to be a little lackluster, and Sony seems to have put a high quality screen in the Vaio Z.
I think for a 13 inch laptop the Sony is top notch, and for a 15 inch laptop the rMPB is top notch![]()
By hardware, I was mostly talking about trackpads. I've had numerous issues with non-Apple trackpads.
Not arguing that the Sony isn't a great computer; I just personally don't see the appeal of it over the RMBP at the same price, especially since you still need to buy an external graphics card to make it as good.
