Title says it all. I want a rMBP 13. It's supposed to replace a Dell Latitude I bought in 2006 for sorting and editing 5D II raw files in Photoshop CC. I assumed (a bad word) this wouldn't be a problem, but when I booted Photoshop CS6 on more than one rMBP 13 in the Apple store, I ran into severe lag. The first warning sign was that ACR responded to slider adjustments about as fast as the Dell. The Dell from eons ago with a Core Duo. The second was that all the basic tools lagged the cursor. Lasso, brushes, whatever. Animated zooms had a slight stutter. Someone please tell me that this isn't normal, that it was fixed in CC, and that I don't have to abandon what appears to be the best system on the market because it doesn't like the program that put it on the map. Seriously, please. I want to buy this thing.
