me too so now i m using those jelly cases to protect... depends on your usage also.. if you change phone regularly you of cuz wanna preserve the value but if you gg to use the full 2 years then doesnt matter that much.. your ease of use is more important then..
Also are you very rough / careless? if you are prone to phone dropping i suggest you keep the armor on.. or get those otterbox/uag when it comes out.. (disclaimer- the screen is so big so essentially its a larger pc of glass that may shatter or crack so really.. dont drop!!)
if you just scared of scratches and usage marks then those really thin TPU/jelly case will work for you just fine.. they're cheaper too.. range from $8-$15...
I change cases alot cuz very bored ma.. i am switching from the chio but bulky cases, to the thinner lighter cheaper ones back and forth. reason is it feels like a new phone each time and thus does help a little in alleviating the itch
