The operating system is probably the best part. I think that the s3 were designed for more response than the s2. The s2 has a lot of delay more than the s3 with better cache and ram, I'm sure the s3 had the gs2 best parts, but I think that if you're a s2 owner, the changed aren't with another upgrade until the big change, right now after one year it didn't seem so significant to by a s3 unless it was the observations version, Wolfson sound and a quad core processor is pretty cool which will enable voodoo sound and hopefully for big time processes at once like calling downloading browsing and music or navigation at once without a glitch, that is the big difference, I funny know how the international and the us variants did in multithreaded, but it would seem a quad core can do the job at a healthier pace. The kernels are probably healthier as well in time span to better props.
