My take on this is the other way around - I think it's fine on the retina display and really needs to be turned off for the MBA TN displays. YMMV!
I don't see any difference either way. Of course, my old eyes don't see any difference between retina and non-retina, either.Disable LCD font smoothing in preferences/general

I tried it off, but I hated it. I need the bolder fonts to see them clearly with my old eyes.
