I've got a 256GB/1.1 Gold on order. Already shipped. I did play with one on Friday at a local store here. They look awesome, however, I noticed some pretty slow and choppy animations when doing things like: opening and closing mission control, swiping between spaces, opening and closing the notification center side-bar, minimizing, maximizing and dragging around windows, etc. I usually had just one safari or one finder window open when performing these tests. Scrolling through the sites such as the verge were buttery smooth! Did anyone else experience this? I haven't seen any other comments on it yet. I currently use a 2010 Mac Pro at home, and a mid-2013 MBA 11"(8GB, 1.7 i7). I did buy the 2012 rMBP when it came out, and I recall the store unit suffering from similar issues. But I don't believe the unit I actually purchased suffered from such slow frame rates as the model in the store. In fact, I believe that people were posting at the time that Apple runs some sort of software that causes slow downs on the demo units. Is this true? I'm still excited, but hoping the animations aren't anywhere near as slow as how I experienced them in store! Edit: I forgot to mention, that I did most of these tests in the highest possible scaled resolution (1440x900).
