Hi all I managed to sell of my 2010 17 i7 1 hour before the official announcement..PHEW! I then drove 300kms to my citys only official Apple Retail Store and purchased the 2.2 15" 1440x900 success.... Then I get home image everything over from my previous system and fire up Adobe Lightroom to do some raw editing....... THIS SCREEN RES sucks. My question is how much more real estate does the 1680x1050 offer? Is there going to much real difference or am I screwed - I don't want to have 2 go 2 a 17" model again as it was monstrously huge to me and really am not interested in having to use an external monitor. I also noticed the gloss screen is much dimmer than my previous antiglare screen. With my old screen brightness would stay at half maximum, on this system it needs to sit at around 75%...Thoughts????
