Given how much time I spend actually using my laptops in clamshell mode, I changed the rMBP for a MBA and put that money towards a 27" display. The added value is that I can keep my ethernet cable at work plugged into my display (as well as any usb drives) and just plug two cords into my MBA and I'm ready to work, including charging. I may get a Belkin stand and use the MBA as an extra screen at work. Loving the MBA so far and although the retina is remarkable, it didn't make sense for me. I absolutely love the service Apple gives its customers. From the class my wife and I attended, to the return process of the MBP, to the upcoming 1 on 1 training, to transferring data from MBP to MBA - it's all be remarkable. Thanks for the advice guys. Sincerely appreciate it.
The only thing I don't love about the Macbook so far is that the fonts are so small on everything! I feel like I need reading glasses to see what my tabs say on Chrome or read the font. And when I zoom in, the buttons aren't aligned correctly :/
