I agree. In fact, that might be a deal-breaker for me. I currently use the 3500mAh high capacity battery in my EVO. Moreover, I have a couple extras to swap out when I'm not able to recharge my phone. This 2650 mAh battery is almost 1/3 smaller than the current maximum capacity one I use, which means it's likely to run down more quickly, and since I can't swap it out--I'd be forced to plug it in somewhere--I'm effectively without the use of the phone during the time it's charging.
Who's the "genius" who thought of this? Some iPhone wannabe???
