I have been spoiled by the display on my new RMBP! Switching between it and my 24" LED cinema display is painful (especially when I have them both running at the same resolution)! I saw this article from Cult of Mac a while back and it basically outlines that Apple doesn't need to increase the resolution by much more to attain Retina levels on the iMacs and Thunderbolt display. http://www.cultofmac.com/168509/why-you-might-be-disappointed-by-the-resolution-of-those-new-retina-display-macs-feature/ Yet, the required resolution of 3840 x 2160 for a 27" retina display seems far off. I also worry because Apple is shipping Mountain Lion with 3200x2000 wallpapers. I wonder if this is an indicator that we will not be seeing retina iMacs and Cinema display for quite a while. What do you think?
