Yes, I am excited about the camera also.
I have been putting up with the crappy camera on my Moto Droid 1 (launch day) for almost two years now. My wife got a Droid 1 about 2 months after me and her camera is SO much better than mine. I guess they fixed whatever issues they had with the initial batch. I tried getting Verizon to replace it, but they wouldn't.
I have been drooling over the picture quality that my sister gets with her iPhone 4, so I am stoked that the 4S camera is even better than the one on the 4.
