Yes, a tough decision especially since the One X screen has better sunlight viewing. But in the end, Samsung has added many more features, as well as the device having REAL multi-tasking unlike Sense. And the ability to increase storage with a 64 gb SD card and have a back up battery makes the GS3 superior. I don't think there's a perfect device including the new iPhone. But in the end, it's personal preference. The GS3 is thin, fast, sexy, full featured and has an awesome screen, as well as being built by a solid company. You see very few people having to exchange their devices in comparison to HTC also. I've had mine for about 5 weeks and it has been flawless from the beginning. And I get GREAT battery life with it too.
