I have the Body Glove and I have no problems with it. It may add a little bit of bulk and weight, but the protection seems to be worth it. My fingers do bump a bit on the top row of keys, but for me it's no big deal. I'm also not too fond of the keyboard, and have found the screen keyboard easier in most cases.
I've taken the case on and off a few times, and don't see any scratches to the body. Besides, once the Body Glove is on, you really have no reason to be taking it on and off unless always pulling out your battery or SD card.
Fits nicely on my hip too.
I wasn't sure what I wanted, but my Verizon store was very helpfull and let me try each option they had to help with my decision. I'm very happy with it.
I also have the Verizon screen protector on it. I used all 3 to get it right and without dust. Failed on all 3 attempts so the last one stayed on as is. Very much a finger print magnet. Ghost Armour just arrived today, so that is going on next.
