I have a few in my collection. My original ones do have better battery. I'm yet to pull the trigger on the 3, but when I do I'm doing the external battery idea I had since it will mostly be used just to take photos.
Battery life is advertised on the Hero3 Black to be just over an hour. You get another 15 minutes if you don't use WiFi. The Battery BacPac helps a lot of you don't mind a little extra weight.
You would think that this is SUCH an issue for so many users the GoPro people would figure out how to make better than a 1050 mAh battery (unless they know that by making only a 1050 battery, they sell more $20 batteries).
