I have a more recent 22" (the 20,xxx one made so far)
The colors are actually exactly the same as the 23" very light silver (I had my old cinema traded in for a newer one)
The picture from apple of the 22" is not only old, but taken with a bad camera, since it's lighter (and on newer models you have a very light grey logo)
Plus the signal cable is opaque grey like that on the quicksilver power cord, etc.
The one thing I was really upset apple didn't keep was the power button on the bottom bezel like on the standard cinema, it's a trademark in how you can tell if a picture is genuine or not

[plus you don't have a big huge light blaring in your face!)
According to apple, the HD (23") displays High Definition video, yet if I have it right, both models do since HD is such a low resolution.
IMO on the list the 22" is still a much better value per pixel (or resolution, etc).
The prices in the US:
23" $3499 [152.13 per inch ] 2304000 pixels @ 0.001518663 cents each
22" $2499 [113.59 per inch ] 1638400 pixels @ 0.001525269 cents each
17" $999 [ 58.76 per inch ] 1310720 pixels @ 0.0007621765 cents each
15" $599 [ 39.33 per inch ] 786432 pixels @ 0.0007616679 cents each
More detail, if not enough up above (the 15" is basically the best "value" but which is the best in detail?)
23" has 100173.90 pixels per square inch [PPSI]
22" has 74472.73 PPSI
17" has 77101.18 PPSI
15" has 52428.8 PPSI
Embarassingly, the 15" has half the PPSI as the 22"
Now we go into brightness, if I remember correctly:
23" 200cdm / 350:1 contrast ratio / 160 degree viewing (both ways)
22" 180cdm / 300:1 contrast ratio / same
17" 200cdm / 350:1 contrast ratio / same
15" 230cdm / 300:1 contrast ratio / 120 horizontal, 90 vertical
Anywoot, after rambling off a crapload of specifications, there are other things to note such as the smoother look of the new display (shrug) etc
I guess you get what you pay for, but the 23" is still, in basic, very much more expensive for just 1" and 665600 more pixels (sigh) very long and complicated though.
For professionals, the 23" will definately cast a huge shadow on the 22", and I bet that's apple's major plan.
I hope this post actually has some use
