The pros are only size related. Size at all costs is excusable as a consumer or prosumer product, but most of the users of the high end pro's want power, cooling, good ports, reliability, and certainly upgradability. The 2012's were so nice featuring 2 internal sata connections and removable ram. Those computers weren't too thick in my mind, so for a pro, I think they have their objectives mixed up.
