No, I haven't used either device. S3 might have better reviews, but if "beautifulness" is important to you, I think the One X is much better looking. Everything I read makes the One X sound like it's at a least among the best 3 or 4 phones out right now, so although it might not be as good as the S3 overall, it's probably pretty good. And it apparently has an outstanding display, which I'm guessing is something you value as well. Not trying to push you either way, just saw that you were looking for a good looking device and thought I'd point out the One X if you weren't aware of it.
