You can see the issue here http://craftymind.com/factory/retinascaling/retina.html
Have you tried running the native resolution? It gives you tons of real estate and avoids the retina compatibility problem, assuming your vision is good enough :)
You can't get the native resolution from system preferences, but there are some utilities that make it pretty convenient to get at it: http://osxdaily.com/2012/06/18/3-ways-to-run-a-retina-macboo...
I recommend SetResX on that page, it's free and works really well, and just sits in your menu bar. Just watch out on the downloads page, there are a bunch of ads that look like the download link, make sure you get the right one.
I've settled on 1680x1050 for browsing and jump up to 1920x1200 for coding.
The web side of things is a different story. AFAIK, there isn't even a nice way to send hires images to hires displays without adversely affecting those browsing with standard DPIs.
The only game I've played so far on my new rMBP was Civ V, which supports Retina in that its buttons and controls are blocky and double size and the map itself is rendered at full resolution.
