I probably already know the answer to this, but looking at getting into the surface lineup whether it be the normal version or the pro. My question is, with the regular surface would there be a noticeable change in performance against a machine this old even though it has on the surface (no pun intended) better specs. Wondering if optimization has gotten to a point where the surface can perform as well as this older MacBook, so I can make the switch and divine the wife as well.
