Except it is double the thickness of a MacBook Pro, and the touchpad / touch screen is not really ergonomic (it requires carrying around a mouse). It may be more powerful, but not as portable as a MBP.
But how horrible is the thickness "issue" at this point, unless one makes a living entering/exiting rooms by crawling under closed doors?
With every fraction of thickness taken away from any of the MacBook line, all I see is all the lost opportunity for more expandability, more battery life, more keyboard/touchpad feel, more ports, more More. Size doesn't always matter.
