That Studio just blows the imac away without even trying, incredible. I'm a bit bummed that the surfacebook doesn't have kaby lake, or that they didn't update the surface pro, but there is always next year.
I think the lack of KL is for the same reason we won't be seeing it on the MBP tomorrow. Intel doesn't have it ready yet.
