I agree that working with a "retina" or other high resolution display is a new experience and will require some adjustment. The problem is not really that those displays are high resolution it is that there are still plenty of "low" resolution screens and people are wanting to design for an average. Standards are going to have to evolve. Really if you want to see how your image looks on a standard resolution screen you have to use a standard resolution screen to view it. If you want to see how the image looks in a web browser on a retina screen open it in a browser. That is not the same as it is interpolated up. Also the Apple 15" retina screen only displays images 1:1 or at exactly 2X when the screen resolution is set to "best for retina" 2880x1800/1440x900. If you are using one of the scaled resolutions, as I do, it gets much more complicated. It is confusing that different tools have different interpretations of the screen resolution.
Images are not going to look perfect at anything other that 100%. There is no way for PS to display images larger without interpolation, which is what Preview and Safari etc... are doing.
There is a good expatiation of the retina display in AnandTech.
