Finally got the chance to play with a one tonight.
Wow, just wow. The UI is ultra snappy. Reminded me of nexus 4 right away. Almost one hour of installing apps, running them, setting widgets, and still not even one stutter. AMAZING job by HTC. Amazing....
Sense 5 gets a 9.5/10 from me, with stock getting 10/10 of course. That's how good sense 5 is.
And the screen. Wow. It is like the best screen I have ever seen. And this is coming from an iPhone 5 daily user.
And I checked out the gs3 and note 2 again just for fun (no gs4 in stores yet). My gosh, now I remember why I went back to iPhone. That AMOLED looks terrible to my eyes. Sorry to amoled fans, but the htc one LCD destroys the amoled. I am sure the s4 amoled is a step up, but amoled is not going to beat LCD in whites, which is what I prefer.
I didn't get to test camera however.
I have a question for all you htc users: take a picture of a typed letter (or any document, anything that is not confidential to you

) and post it please. All I want to see is if the cam does its job in that scenario.
And if it does, I have probably found my next android phone
