I'm sitting at my desk trying to figure out my next upgrade. I don't need a portable 15 MBP anymore (currently have have it connected to a 20 inch cinema display) - I'm going to put the 20 inch where the 15 is, and connected it to a 27 as a second display. The only problem I see is - that the 27 may be too close to my eyes. I was wondering if you guys could comment on how far you sit from your 27's and if you adjusted and love it, or had to modify your setup. Here are my distances. The front of the 27's screen will be 18 inches from the edge of my desk. When I sit normal/close my eye balls are 22 inches away. When I lean back (which I do often) my eyeballs are 33 inches from the screen. Thoughts? I really don't want to get the 21.5 because it limits me on Max ram, Video card, Processor and option of SSD. Thanks!
