Agreed on liking the battery aesthetics... I'm charging it now while powered off, but I held the phone and I have to say I'm very happy with it. It retains the styling they were going for on the back, but the pictures don't do it justice. The pics make it look much more awkward than it really is. Plus, it defintely gives the phone a better "feel" in the hands. Can't speak about performance yet, but I am VERY happy I decided to purchase the bigger battery...
Oh, and Makya? I, like yourself, am a pretty big guy... The extra weight is great! I think it will be just what you're looking for based on many other posts I've seen from you. However, it's not a huge weight gain, so it won't turn away those of you looking to keep the phone light. The phone now weighs exactly 5.50 ounces... The specs off of VZW's site are exactly what I got as well with the stock battery, 4.59 ounces...
