I really don't understand the love for the mute switch. It gets dirt stuck in it, it flips accidentally when you put a case on, and for people like me who leave their phone on silent 100% of the time (a growing population now that the Watch is so common) it is a 100% useless feature that I'd give up in a heartbeat for something programmable or otherwise more useful. I do hate how unintuitive power/reset sequences are now, and I hope they simplify. I never have used my side button for Siri... that should be programmable to something else too.
