So i was tossed between the MBA and the rMBP, as well as 13" vs 15" However, my boss gave me the nod that I can expense it, so fully upgraded 15" rMBP it is I have 2 monitors on my desk with VGA/DVI inputs. What is the most efficient way to connect these so I can run a monitor on each side of my laptop, and also utilize the laptop screen? So drag-right and it would drop to my right monitor, drag-left would go to that one. I think I have 2 thunderbolt ports, and presume I can just buy 2 adapters? or will that not function as i want? Should i look for a single thunderbolt plug with a 2-monitor splitter built in? Thanks! Loving the machine so far.
