Just trying to get an idea of how many 15" rMBP owners use their laptops with an external display when sitting at their main desk. Before I got my rMBP I was rocking an old plastic non-unibody MacBook as my main machine paired to a 20" Dell 2005FPW LCD. With my old setup I had the Dell central on the desk with the MacBook off to it's right side and that worked fine. But now that I have the rMBP I have since removed the Dell from the desk because the rMBP's screen quality is just so good compared to the LCD. Plus it was a lot easier to get away with a 15" screen than a 13" screen as my only screen. Every now and then though I wish I had more screen real estate. Just wondering what you other rMBP owners have set up at your desks and what do you find works for you? Also, if you do use an external display with your rMBP do you have your external display centred on the desk with your rMBP off to the side? Or vice-versa? In the past when laptop screens weren't as good in quality as desktop LCDs it made a lot of sense to use your external display as the main display.. but now that these new retina displays are out it's not as clear anymore how to setup a laptop + external display desk setup. Well, at least to me anyways. I'm looking forward to hear your responses. Thanks guys.
