Anyone who doesnt case up their shit whether its android or apple is a fool. That device cost money and 30 bucks for the case is a sound investment to protect any device. So you dropped your uncased device once, maybe a couple of times and there wasn't any damage, guess what... you were lucky is all. Eventually that luck will run out and you'll be posting a bitch an moan post about the ding, dent, scratches, cracks, and unresponsiveness that your device has due to dropping one to many times. Brand doesn't matter, but little things like trajectory, velocity as well as the density of the surface you dropped it on does, so does the fact that maybe your device was assembled by the employee of the month while someone else's device was assemble by the company idiot. Be smart, case your shit, it'll last longer.
