Bought a couple Sprint HTC ones to sell - one I kept and am planning on unlocking before I sell. Meanwhile I've played around with it.
I've never been a fan of HTC Sense but it has greatly improved. Like the look and design.
The phone feels really good in the hand. It's a bit more narrow than the Galaxy S3 which was just too big for my hands.
The aluminium design is really nice.
When I first turned on the phone there was NO bloatware on it. I thought this was great, but after activating it on one of my lines all the bloatware downloaded and appeared. Oh well, most can be uninstalled.
The screen is really nice and the colors are great.
Small feature I thought was nice was being able to use 2 languages of auto correct at the same time.
Also, like I mentioned above I was thrilled they left all the languages on the phone so you can actually turn the whole menu/phone to Hebrew as well as a bunch of other languages.
The camera has a boatload of features and editing options. The S3 and iphone 5 still take better shots in my opinion but for a lot of people they won't notice the difference much.
The speakers get LOUD!! If you watch videos or play music on your phone often you'll def enjoy this.
You are able to turn off the shutter sound. This is something that isn't always available on other phones.
And the wifi works very well. On my Galaxy Nexus where I have 2 bars, I am getting full bars on the Htc One.
The only thing I am waiting to see is how battery life stands up. Maybe I will actually keep one of these for myself since it also has a removable sim card and can be used overseas. And yes you can change the APN settings as well AFAIK.
Oh, the IR blaster works super as well. Fun added feature to have on your phone. The GS4 will have this as well I believe.
