Pink Cinema Display? Yes
While I don't own a Cinema Display 23 (yet), I went to some local stores to check them out.
Well, I saw two new 23 inch Apple displays, and they both are pink. At first, I didn't notice it and thought "nice, they're all right", but then, when I compared them to a 20 inch Cinema Display standing next to them, I saw the problem. Grey areas (like iTunes window) look a bit red/pink on the 23", but very neutral grey on the 20". Other colors, like green or blue, don't seem affected.
I tried to fix the problem with the expert calibration. You can change the white point to about 8500K, then most of the pink hue disappears. But then, the rest of the image looks very blueish.
It's not Apple's fault, it's the LG panel they're using. It is a bit pink and will be. Other displays which use the same panel (like the HP L2335) will have the same problem. It will only change once LG releases a new panel version, which could take about a year.
However, remember that if you don't know about the pink or if you don't have another "neutral" display to compare, you won't notice it. But it IS there.
