I was just on Seidio's website and they're currently developing an extended battery for the Storm. They say its capacity is 90% better than the standard battery. Now with that being said, I don't mind getting an extended battery (I pre-ordered the 1600 mAh already) but the 2600 mAh is supposed to be better but then again, it gives a bulky look to the sexy Storm with such a huge replacement door.... anyone think about getting one???
