I love this phone!  It has a beautiful, clear, bright screen that I can read easily outdoors even with power saver mode on.  It feels solid, it''s easy to hold, but it''s not heavy or thick.  The performance is good enough that I don''t even know what tasks are computationally intensive anymore.  The battery life is great. I typically spend 30-60 minutes a day reading books on Kindle, plus some time reading articles online, checking e-mails, etc. -- if I do this, the battery never seems to get below %70 by the end of the day, and sometimes I''m even able to go multiple days on a single charge without getting close to empty.  I''ve been able to do GPS-guided drives around the city and still use my phone for other stuff, which is something I couldn''t do on my old phone due to the high battery consumption of the GPS function.On top of all that, the phone has great audio.  It doesn''t make a huge difference for phone calls, but for listening to music you can really hear the difference between the One and other phones.In terms of software, it''s OK.  I hear a lot of people complain about HTC Sense, and it was a little frustrating to navigate the UI for the first week or so.  After that, I reconfigured the home screen to show apps instead of the newsfeed thing and I feel right at home.  Before this I had a Motorola Triumph with an older version of Android, and I''ve noticed that a lot of the things I used to install extensions for (fine volume control, changing tracks with the lock screen, quickly enabling/disabling wifi, etc.) are built into the OS and work great.I bought this phone because I wanted to treat myself to a best-of-breed phone after my previous budget smartphone started having speaker problems.  It was going to be either this or the Samsung Galaxy S4.  I can''t really know for sure if I made the best possible choice, but I absolutely have no regrets about choosing the One.  I like it enough that I''m not really that curious about whether another phone might be better -- it''s pretty much everything I want in a phone right now.
