The original HTC One was one of my favorite smartphones from 2013, but it was easy to see why you'd pass it up in favor of an archrival like Samsung's Galaxy S4 -- it just didn't have the battery life, camera quality or expansion to keep up. Fast-forward to 2014 and it's a different story. Most of those headache-inducing flaws have been fixed in the new One; indeed, my colleague Brad Molen suggested it was an all-around better device. But is that enough to avoid a twinge of buyer's remorse, especially with the Galaxy S5 and Sony's Xperia Z2 upping the ante? I spent a few weeks with the new One to find out whether I'd still be pining for features from those other devices.
