I've been an iPhone 4 and 4S user, but this month I'll be replacing it with a Samsung Galaxy S3. I've been testing it for the past 2 months now and I must say I'm very impressed. The US version will not have the 1.4GHz Exynos 4 Quad core processor, but rather a Snapdragon S4 MSM8960 dual-core 28nm SoC, clocked at 1.5GHz with the Adreno 225 GPU. It'll have increased RAM (2 GB) to make up for the drop from the quad core. In my opinion, I prefer the Snapdragon and increased RAM more than the Exynos, despite the fact that the Exynos was the staple "future tech" of the Galaxy S3. Reasons being I don't game on my phone, so there's no need for the GPU that the Exynos offers, and the increased RAM in the US version will be nice for multitasking and running more apps. Battery life will also be longer with the Snapdragon over the Exynos. Seems we got the good "shaft" so to speak. If anyone's curious, the reason why the US couldn't get the Exynos processor was due to our retarded 4G LTE networks. They were incompatible.
