I prefer the hard buttons, but it's not a bit deal either way. The only button I've ever had wear out was on a 5 year old iPod. I've never had a monitor, mouse or phone button wear out on me. They're usually rated for tens of thousands of operations, so it's rarely an issue. It's nice being able to hold the device where the buttons are and not activate them. My S4 has the hard home button and soft back and settings buttons. I find either I, or whomever I'm handing my phone off to show a picture to, more often than not accidently hits the back or settings button. It just takes a touch and no pressure to activate it, so it's much easier to hit on accident, but not really any easier to hit on purpose. I actually miss the search button that the older Android phones had. Forcing developers to standardize where the most commonly used buttons were was one of the things I liked about Android. Getting rid of set locations for those buttons moves away from that.
