I was able to test a Retina MacBook Pro for a couple of days but I didn't have enough time to really test everything. However, when I tried several games it seemed like the scaling didn't work that great and the UI elements were tiny and changing the resolution didn't always fix it. For example, Source engine games (Half-Life) always displayed tiny UI elements and if I decreased the resolution then it was extremely fuzzy/blurry. Lots of other games had this same problem. Am I better off with a Macbook Air using native resolution for light gaming? I'm really torn between the two machines because Retina with text look AMAZING, but graphics/gaming suffer quite a bit with older applications and non-retina applications and games.
