I have been checking my local stores and they do not have them....
Mine does, I checked them out yesterday.
I'd say early adopters will have a couple "disappointments" until everything is updated to retina graphics. I opened updated apps like Aperture, iPhoto and iMovie, they looked great on the RMBP. But then I opened Pages and Keynote, which haven't been updated yet, and everything looks blurry. But that'll change eventually.
Surfing the web...honestly felt about the same. Sure, font was really crisp when I zoomed way, way in but nobody reads articles zoomed way in. Watched some 1080p video (the retina MBP ad, natch) and it worked flawlessly, but almost seemed fuzzy as well. They need something higher res than 1080p to take full advantage of this thing.
It seems to me honestly that the larger the screen, the less the "retina" is noticeable. Put an iPhone 3GS and an iPhone 4 side-by-side and you can tell the difference in the screens from 20 feet away. An iPad 2 and new iPad, it's noticeable but you have to get look more closely. The retina MBP, aside from the dock, it just wasn't as noticeable, unless you're doing big zoom-ins on high res photos or fonts.
Edit: Truth hurts, huh? Sorry to **** on your parade guys, but this is coming from someone who does graphic design, photo and video editing for a living and I don't wear glasses either.
