Today I must have read at least four or five threads regarding the home button the the 5s. Examples were the clicking sound it makes, the home button being raised a little and the colour of the ring wearing off overtime. It's going to be different, there's a fingerprint sensor behind the home button. And yes, it probably will wear overtime but just enjoy it while you can. For me personally, I love the Touch ID, it's ridiculously fast. Mini rant over!
