When you are trying to push 100% more pixels with only around 20% more GPU grunt, you're going to have lag. I have a feeling that the animations would be a lot smoother (and battery life a lot shorter) if the GP forced their laptop to use the dedicated graphics card.

Nah, Expose is not that slow on a rMBP. Some dropped frames (three, four), maybe, but perfectly smooth otherwise.

  This is a recording of the "show all windows" command (cmd+F9) on my machine: https://dl.dropboxusercontent.com/u/12091499/Share/slow_expose.mp4 https://dl.dropboxusercontent.com/u/12091499/Share/slow_expo.... It's that choppy.

    Well, for me it isn’t and I also have a rMBP. I believe you, it’s just that you are likely looking at a software issue. (No doubt that this software issue is likely exacerbated by the requirements of the screen and it sucks either way, but in principle the graphics hardware is up to the task.)

      If I close Chrome, Sublime Text and Terminal it gets close to normal speed. Exposé seems to scale very badly with the number of apps running. It's also possible that some of these apps are badly optimized redrawing themselves in some way that slows down Exposé.

Isn't it 400% more pixels. Retina should be 2x the width and 2x the height. Anyway. Mine is slow too. With the nvidia card everything is mostly fine, with the integrated intel card everything is mostly sluggish. There was a review of the 13" retina when it came out saying that the intel gpu was terrible and that he sent the laptop back and was going to wait for the next generation.
