I recently acquired the rMBP, having tons of fun with the machine btw, and am wondering what's a good external display hook up for it. Currently there is no indication of when apple will come out with an updated Thunderbolt Display, and I need something to tide me over until they do. My last external was an apple cinema display from 2005 and is now near unusable. So if anyone has any recommendations, I'm all ears. Thanks!!
