I tend to agree with you... and definitely feels bigger in your hand than the PS HD when it's on the phone. I'm wondering if it's all in our heads.
I agree the NGP is too bulky, mainly in its thickness. Compared to the Apple Bumper, its a good 2 or 3 mm thicker. Feels thick like my old 3G or a Blackberry. Width and length seems the same as the Bumper...but maybe a tat larger in both dimensions.
Reading all these great reviews, I purchased the last one that Walmart had today. I wanted something to add to my collection of black bumper and Sena Ultra thin pouch (for when I go naked). Within 2 minutes, I was sorry I spent $20 on this thing.
Obviously many here like it. But to balance out the comments, I'd give it an 'okay' and probably it is more for the user who drops phones a lot. However, the official Apple Bumper is the nicest...and if you add screens to the back and front, it is well protected.
Some points on the NGP:
1. Goes on easily...but a pain to take off. Not for me since I change cases sometimes.
2. The non stick surface is a little slippery...I like the rubber of the bumper better.
3. It does not seem to affect flash photos...that's good. They made the lens/flash opening larger enough...but it takes away from the look.
4. The smoke finish, while nice, takes away from the slick back of the phone. It fogs out the crisp apple logo and jet black finish
5. Feels thick in the hand, and just doesn't give a 'pro' look. My wife has a $9 case from the mall kiosk that looks the same, but fits better in the hand and looks better too. I like the boxy look of both.
So my NGP goes in the drawer...and I'm back to the black Apple bumper and brown Sena. The Apple bumper is well engineered and performs well, not only for 'antennagate'.
