So, there is no denying that images on non-retina-ready Web sites are bound to look fuzzier on the rMBP in "Best for Retina Display" mode than they do on a non-retina display. Indeed, granted that Lion and Mountain Lion essentially try to find 4 times as many pixels in the same files, the scaling of images designed for old (non-HiDPI) displays can only be done using interpolation, which entails loss of detail. Now, apps are a different story, they will be updated sooner rather than later. No doubt about it and no problem about that. The Web, however, is not going to be retrofit any time soon, if ever. Sure, Web sites currently under heavy development and highly popular Web properties will be updated. But, there is no doubt a majority of Web sites will never be retooled to serve @2x images to rMBP users. (They may not even have the original assets needed to generate those @2x images.) So, it is very important to understand how bad or how good the Web looks currently on a rMBP, because it may look that way for a very long time. What's your take? How is it?
