I have a 15" Early 2011 Hi Res Anti Glare and a base Retina MBP. I put them side by side and go back and forth. Been doing it for days. Changing settings on the MBPr up and down. Surfing the net, working iphoto, playing games, Facebook whatever. The hi Res screen is one of the nicest I have every owned. Bright and excellent color. However, it is not the Retina. The Retina is just as clean and crisp as anything I have seen to date. I do want to say that to me it is not like the Hi Res is inferior or I say what a huge difference, but like some posters say, no going back now.
