Review: iPhone 3GS

Good review. Makes me happy I didn't drop the 500 bones for the new one since I upgraded to 3.0 on my 3G and got most of the function. Quick question though. How did the battery life compare to the 3G? And of course, do you think Apple will bring the new polymer battery technology to the iPhone next year? I'm seriously going to wait till next year, as I suspect that it will happen, and a few other larger things.
