Capactive or On Screen?
As for me, I sincerely hope the buttons are capacitive. I've never been a fan of on screen buttons for various reasons, not to mention. If they are on screen buttons, what the heck is the big black strip at the bottom for? It holds the HTC Logo, sure, but if that's the only reason, then make more use of it. Put some freaking buttons there. Lol. I absolutely love my HTC One 2013, and I'm more than likely getting the 2014 model (which i really hope is called the One Up as some rumors suggest), but the on-screen buttons kill me.
I'm tech savvy, but I'm far from a Dev. I am, however, always willing to learn, and welcome being corrected and taught new things!
