Just know that the extra bulge on the back becomes an issue if you like to use a protective case. Most manufacturers will not have a case compatible with the extended battery, although a select few will eventually down the road. If you can deal with the extra bulk, then you should enjoy your extra battery life! For this reason though, I think I'm going to go with the smaller one myself, even though it is not that big of a jump (it's always good to have an extra battery lying around).
