Hey everybody, I'm just about to go get my 1st smartphone (at least I don't THINK my LG Voyager is a smartphone) which is going to be the Droid RAZR. I've got a lot to learn, I'm sure, but figured I'd introduce myself here and ask my 1st question! Before I go get my phone I figured I'd buy some protection for it, so I'm not walking around for a few days to a week with it unprotected. Last I remember it's a gorgeous looking phone so I'd prefer to keep it thin and un-obscured. So, does anyone know if there's any real difference between the Ghost Armor, ArmorSuit, and Zagg InvisibleSHIELDs? They all seem relatively the same at first glance. Also, are these really sufficient protection for a smartphone? Thanks!
