build quality is extremely high...

the back of the polycarbonate is so smooth it is smoother than the skin of your girlfriends!

micro drilled holes cannot be felt despite seeing it with your eyes..

the phone build just screams premium!

any ideas on how to port the new HTC keyboard to other phones??

Great Build Quality
Great Camera
Awesome Display
Awesome Game Performance
Good sound output
Good HTC based widgets (Not all of them)

It's truly an amazing device... Ignore the troll you see ... People tend to scrutinize a minor problem into a whole lot bigger. Trust me it worth every penny I send on this device. It makes me happy that all it matters

Screen is super sharp, real threat to other company's.
The body feels premium and feels great in hand propebly not the same as my girlfriends skin but close
Camera super fast I hope they keep up with that technology.
Sense is improved a lot too.
There will not be much new tech coming in to the upcoming phones from other companys.
HTC did a sucsessor here.

Build is nice, 4.7 inch and still fits in my jeans without any problems.

The overall speed of the phone...it takes longer time to say "sigh" than installing a big game or a big app.
Lightweight, my previous 4.3 inch HTC is alot heavier.
Camera is outstanding, especially the burst mode, almost sounds like a DSLR.
Screen is outstanding quality.
Smooth gaming, tried a few Tegra 2 games.
Sense is very smooth. I still miss some functions from sense 3.5. (Quick launch menu)
And one thing I like in general about HTC phones is you get a screen and nothing else.
If you look at a Samsung (SGS2, Nexus) for an example, you'd get a ton platic around the screen that makes it look big but nothing else and probably won't fit in your pocket.

Good job

...and hey...it isn't just expensive...you get alot for the money.

The camera. Simply incredible from first test.

What I love

---

The most obvious thing about the One X is its screen. It is truly gorgeous - I could just stare at the home screen all day. One thing that pleasantly surprised me was the brightness of the screen.

Sense 4.0 is really good. I know a lot of people really dislike all skins (and I do tend to agree with them) but I do think that sense brings some good features to the table without getting in the way of ICS.

Power - everything runs so quickly and smoothly. It can handle anything I can throw at it.

Build quality - I don't know how sturdy the device is but it certainly feels premium with the matte unibody and the precision laser drilled holes. I get the feeling it can be dropped without too many problems (not that I'm going to test that).

Camera - I haven't tested it properly but I can tell you it takes pictures very quickly

As others have said, its:-

Screen - the best HD phone screen I've used.
Build - manages to combine solidity with design flair (its like a solid Arc )
Camera - massive improvement on previous HTC efforts imo - took some great family shots yesterday.

in that order as the things I'm most impressed with.

I actually quite like Sense too and now I've reduced the number of Screens and Widgets I use, its a lot smoother.

Phone feels fantastic in the hand - completely different league to the plastics of the SGS2 and Galaxy Nexus I owned previously.

If HTC continues to produce phones with this quality throughout the whole 2012 year I think its going to be the biggest threat to companys like Samsung, Apple, LG, Motorola etc etc
