I'm using the 32GB model on Rogers in Canada, I haven't been out and about with it because of a damn stomach flu going around but that's given me more hand's on time with it the last three days.
Build Quality: So far I haven't had any issues with it, other users have reported stuck/dead pixels but on visual inspection and using a stuck pixel finder app I can report that I am completely clean. There is a tiny, as in fraction of a millimeter gap between the top and bottom bezels in the screen but it doesn't feel like a build quality issue, the gaps are even across the whole thing and I like it because it allows me to figure out the boundary of the screen without looking. I also haven't seen any issues with the zero gap plastic, I know some of the early models showed signs of cracking but there is nothing wrong with mine.
This phone gets very hot when doing CPU intensive tasks, GPU tasks it gets warm but CPU tasks you could use it as a hand warmer in the arctic. To figure out what I mean, load up pandemic and play it for about 20 minutes to a half hour. It will actually get uncomfortable when holding the phone, Pandemic isn't very graphically intense but it does do a lot of CPU tasks.
Software: I made the switch from IOS to Android. IOS was really my first entrance to a true smart phone device, prior to that I had a Sony P1i and IOS was miles ahead when I switched. I find that some things done on my old Iphone were simpler to manage. One example of note I guess would be the notes. The note taking app was very simple, I could quickly pop it up and type in a new note and close it. I also had it syncing those notes to my google account as a backup but oddly enough there is no way as far as I can tell to sync those notes to evernote or to the built in notes app on the One. It's not a major issue, I can still access the old notes through gmail but I am a compulsive note taker and use them to reference just about everything. I'll be saving them to evernote from now on to get around the compatibility but it was one of those switching pains.
I'm not in love with sense, I've used other android devices before and I really like the stock android experience. Sense seems to over complicate things, and while I don't think it really removes any features from stock android I don't think it's made anything easier. I'm also not a fan of blinkfeed, if i could add in very specific news sites to watch it would be different but at the moment I look at it once a day and the majority of it I find useless to me.
I think I'm going to have to do some fine tuning on the notification system, I'm not sure if I'm just going crazy or if something odd is happening but I've gotten text messages from people that vibrate and light up the notification light and then others it ignores, I haven't delved too deep into customization on it so it's probably something I'm missing.
The odd app drawer and home screen folder setup. So I'm a bit OCD in terms of keeping all my apps neatly organized and on one screen. I put everything into their proper folders and sort the folders by priority and apps in the folders by priority. It bugs the living hell out of me that if I have a folder for something in my app drawer and make a shortcut on my home screen for that folder, if I then add a new app to it from either the home screen or the app drawer it doesn't automatically show up in the other. It's basically left me with having to do the same task twice over because instead of the folders being actual shortcuts that should technically lead to the same thing, all it's doing is making a duplicate of the folder and then separating them.
This is really just a quick look at what I've seen with it in the last few days. I'm loving the hardware, the customization (and yes the emulators!) on it but overall I think HTC's software side of things fell a little flat. I'm sure I would be happier with a closer to stock android experience.
