After 2 years of loving my HTC 4G LTE, I finally upgraded to the new HTC One M8 (Harmon Kardon Edition) .Been using it for almost a week now and am very pleased. It is worth the upgrade.
Great build, super smooth, fast UI, great sound, loud clear phone quality, and I even like the camera, it is a step up from the the old camera. Anyone on the fence about getting this one (no pun intended), do it. You will love it.
