"The display itself, to my eyes, seemed unchanged from the original iPad. I wouldn’t be surprised to find out that it is the identical component. As I mentioned before, the surrounding bezel is slightly smaller on the iPad 2, and there is less aluminum around the edge, so the overall device is about 0.2 inches narrower and a hair shorter. But the display itself is exactly the same size, and my eyes detect nothing different about it. It is not laminated to the glass like the iPhone 4 Retina Display.
In short: the iPad 2 is a little lighter, remarkably thinner, and feels much more comfortable to hold. For all practical concerns, the display is identical to last year’s iPad."
