Finally made it over to the Apple Store today to check out the retina screen in person. No question that it is a beautiful display. That said, it did not jump out at me as quite as breathtaking as when the iPhone went retina. I suspect that has to do with viewing distance. I did try to put it through its paces a little bit to see if I got any of the lag that people have been complaining about. I tested at "best for retina" and the two higher scaled resolutions. All of them looked equally smooth in Safari, when switching between desktops, and when invoking launchpad. All functions were comparable to my early 2011 15" HR MBP. It will be interesting to see where they take retina next. At this point, I'd like to get away from the 15" form factor. I now dock to a thunderbolt display at home and only move the MBP when traveling, where 15", while still manageable, isn't the ultimate in convenience. That, of course, has to be balanced against my desire for the highest resolution possible -- and the 13" MBP resolution simply isn't acceptable to me. If they release a 13" rMBP later this year as rumors have it, I've probably found my next machine.
