I want a fugly phone. I am hooked on these extended batteries. I've used one for the past year with my BlackBerry Tour and I absolutely love it. If I cared about looks, I'd have an iPhone.
I plan on streaming quite a bunch of video using my Slingbox and the very cool Stream Media player. Between that and my Rhapsody streams, I'm either plugged-in or in need of a bigger battery just to make to the end of the day.
