What do the other resolutions look like? I know in OS X you can't go down (for now) to really (non retina) at 1440x900 and also in Windows (for no new bootcamp driver) you can't; but I see how in the gaming sessions you can choose the 1440x900, how does it look compared to a standard MacBook Pro display with a 1440x900 native resolution?
Because, in theory, it would look identical, without the problem about scaling to non-native resolutions (what happens, for example, when you go to 1280x800 in a display with 1440x900 native resolution), due to the fact who each 4px of retina display becomes exatly 1px at that resolution. There is any one who can try and check this?
