That's another thing I don't get at all. I'm ridiculously happy still with my galaxy s3 (yes 3), plastic back that i can remove in seconds. I've never had a case for it, and because it's plastic, when i've dropped it, it actually has some cushion. It's also thinner than my wife current iphone x with a case on it. What is the use case for aluminum other than "premium feel"?
