The first thing most people notice is that the iPad's shell is tapered much more gradually, which likely will result in a more smooth and sleek feel. Interestingly, Apple made the exact opposite change a few years back when they changed the iPhone 4's body to look more boxy, as opposed to the curve on the edges of the iPhone 3GS.
But, the more exciting aspect of the picture is about the camera. The position of the camera has only shifted a tiny bit to the right, but look at its size difference as compared to the iPad 2. It's significantly larger. This goes along with a rumor that the iPad 3 might sport a 8 MP camera.
The story of the iPad's camera goes back a long way. After the hype of the first iPad's release two years back, many people were disappointed not to see a camera in the front or the back. The iPad 2 came out a year later with a camera, but the resolution was so awful Apple wouldn't disclose it's exact quality. The back camera turned out to have only 1 MP quality, and the front camera 0.3 MP. Some people wanted better quality, but others were satisfied because tablets aren't usually the primary device used to take pictures and videos. But, Apple has been adamantly increasing quality on the iPhone camera despite similar ideas. The iPhone 3GS saw an increase to 3 MP, the iPhone 4 up to 5 MP, and finally up to 8 MP with the 4S.
Yet, camera technology is increasing, and my feelings are that because it is now possible to pack very high-quality cameras into very tight spaces, Apple should feel free to increase the quality of the iPad's camera.
