Ok so i've been going back and forth with the concept of adding an external display to my macbook pro setup. Currently i am using the mStand to elevate the macbook pro in front of me. I'm extremely happy with this setup but feel as tho I need more screen realestate. I've decided that the Apple Cinema Display is the way to go but I'm stuck between the 20 and the 23'' displays. So here are a few questions. 1. Does anyone use us a secondary display to the left of right of their macbook pro, Utilizing your laptops display as the primary display? Any complaints? 2. Do you find disconnecting and reconnecting the display a pain in the A? 3. Do you utilize the ACD as your primary display and the macbook as a secondary? Any pros, cons, or complaints ? 4. Do you think the 20'' display would match up better than the 23'' with my macbook pro 15'' display..size wise? Here is my current setup.
