It's a no brainer. I can now use the phone the way it was meant to be used. NO MORE WORRYING ABOUT BURING THRU THE CHARGE ! Do not worry about the extra bulk, it is no big deal at all. Bought the battery (with the new battery door) and a new case from HTCpedia. Yes, they have factory cases for the extended battery now. I can now crank the tunes, use the GPS with reckless abandon, use ACTIVE wallpaper and turn the BRIGHTNESS to the highest level with no worries. Buy it.
