[AT&T, Rogers HTC One X, Telstra One XL] MyronJ906:
Haha, I'm in the exact same boat here dude. I got an S III and my girl kept the One X.

Because I can never shut up and LOVE this community (I've had many laughs here). I figured I'd give my own subjective interpretation since I now have both in the house and got to play with them side by side.

Regardless of which phone I use, it's going to be an AOSP based ROM, so any Sense vs TouchWiz automatically goes out of the window for me.

The One X, from day one just looked AND felt right. It legitimately felt like a top end premium device should to me. The screen is great, the weight seemed appropriate. The device felt rugged and classy. It felt like power. Couldn't decide between white and grey though, so I got one in white and girlfriend got a grey.

Now I have a white S3 (traded the grey One X for it). First off, NO WAY IN HELL I was getting the ugly blue version. I saw the display model in the AT&T store and--NO. No. NO. It just didn't look right. I'm still not even sure the battery cover was actually blue. Weirdest shade of blue I've ever seen. The red looked tempting in pictures though.

(Back on subject)

S3 doesn't feel nearly as premium to me. In fact, I almost wouldn't think twice about tossing it (if I was an idiot). The glossy plastic just doesn't feel right. To me, it's kind of awkward. The phone seems a little easier to hold than the One X though

Screen quality: The One X is definitely better, especially since I do a lot of night reading and the S3 gets those wonderful (read:ANNOYING) AMOLED ink stains (or whatever they technically are). Fortunately, mine aren't severe but can be distracting. I would prefer the One X screen both by day, and by night.

Button placement: I HATE the power button location on the Galaxy S3. I have gotten used to it in under 24 hours, but still. I had difficulty pressing it without also pressing the volume buttons initially. I think I'm over it now. I like MENU, HOME, BACK as opposed to BACK, HOME, RECENT. I did always use the mod for MENU instead of RECENT on the One X. Ideally, I want BACK, HOME, MENU.

I thought I would hate the physical home, but so far it's a really minor annoyance. Would have preferred capacitive...EXCEPT, I don't want it to COMPLETELY DISAPPEAR. In that regard, I'm glad it's physical. I don't like the whole thing with the buttons disappearing when not in use. Probably because I'm just not used to the layout just yet.

Which device comes off as high end to me? The One X, no doubt. Galaxy S3 could easily contain a midrange phone within its body and I wouldn't think "Man, what a waste of this body". Maybe the issue is that the One X felt like a great Android, and the S3 just feels like a phone. (Talking purely on the body/build quality, etc.)

I don't care about the extra gig of RAM (though it is no doubt useful). After the One X, I no longer care about a removable battery. The SD card wasn't a deal breaker, but is nice. On the One X, I would have made up for it in the cloud. On the S3, I'll just use my memory card. Thanks.

The One X made me prefer a unibody finish. It actually just feels better that way to me, it was my first unibody but it made sense. Gone were the days of constant battery pulling, or worrying about my next phone supporting an SD card.

If I prefer the build of the One X so much more, and barely care about the S3's "perks" then why the hell would I keep the S3 over the One X?

Samsung did something that catered to me and I appreciate that. They released kernel source even before they released the phone. HTC is making us play this waiting game. No one would complain if we got source from some old version. We just want it to get things working in our custom ROMs.

Samsung also released (on most carriers) the phone with an already unlocked bootloader. Once again, that's supporting me and making my life easier.

The AT&T One X wasn't even supposed to have an unlockable bootloader. It's just thanks to the Rogers version and SUPER CID that we were able to make it happen.

Sorry HTC, but this isn't a game to me. We're not playing cat and mouse because I don't need you. Another manufacturer offers a VERY similar product (even with some hardware advantages, like more RAM and an SD slot). Why should I waste my time with you?

I'm just one person, but I hope that other like minded people will continue to show that giving our communities kernel source, and unlocked (at the very least unlockable) bootloaders is the way to go. That's what wins us. Along with quick updates.

Samsung's attitude (in this particular instance. I know it definitely isn't true overall) tells me that a Nexus is not my ONLY option for a development friendly device.

I know a lot of us are not within our 30 day exchange period, and thus trading the One X for an S3 isn't even almost a sensible option since most S3 owners will want cash in addition to a One X. But for those of us that are, if you can live with the S3's flaws then I think that's the way to go.

I'm not going to wait for HTC. It tells them that it's ok to make us wait, because we'll still buy the phone.
