I think the author really wants to have a MacBook Air and not a Pro. If anything, the Pro needs better screens (1440+ matte on 13" please), USB 3.0 support and more powerful hardware to differentiate itself from the Air line.
"We asked ourselves, what would happen if a MacBook and an iPad hooked up? Well, this is the result, we think it’s the future of notebooks."
It made me wonder what would happen if the MacBook Air and the MacBook Pro would hook up. Surely Apple is taking the best of both machines when they are designing the new MacBooks. So what would the ultimate MacBook pro look like? Well, more like a MacBook Air.
