In my personal opinion I would much rather buy the international version, than the AT&T version. (Which is why I did just that.) In my opinion the international version looks much more appealing with the home button, and no AT&T logo at the top. Plus the international version has the Exynos, which is much better than the Snapdragon S3, that will be inside the AT&T version. The only real advantage the AT&T version has is LTE. But in my opinion the international version is much better in every aspect. (HSPA+ is more than enough for the average user.
Plus an added bonus with the international version is not waiting for AT&T to handle the updates, or preload carrier crap on your phone.
Just thought I would say, it's nice to see another Nexus S user moving over to the Note.
