HTC One is the flagship model for HTC. I have been using it for more than a month and I must say that it is a very well built phone. This commercial in Taiwan shows the small little things that HTC has built into the phone (Infra Red sensor and the TV app). Check out how it can change your life (ok, I exaggerated).
Here is the video.
If you think this is good, check out a bunch of them on HTC Taiwan YouTube page.
