A properly designed case leaves the entire screen available. A badly designed case ... it's the same as anything else, some people make great designs, others make designs that are worse than useless.
is that why Reiko is your favorite, it destroys phones?
I don't like bulky cases. I have been using the Verizon's shell case on the past 3 of my phones, never an issue. It never detracts from the look of the phone and has 2 way kickstand. But that's me.
