Samsung Galaxy S III features Android 4.0 ICS with its TouchWiz interface. I've never been the biggest TouchWiz fan, but I found this version a little less intrusive, and the phone navigable and easy to use. Samsung's TouchWiz does add certain enhancements that we'll get to in a moment, so I have to appreciate the layer.
One of the most impressive features is the 1.4GHz Samsung Exynos 4 quad-core processor on this global model. It felt very fast, but of course the data network also contributes to impressions of speed when it comes to data-heavy tasks like loading Web sites and uploading photos.
Since Wi-Fi always struggles within the concrete depths of a convention center, there was some legginess there, but I can't attribute that to the processor. I'll need more real-world tests to really gauge the internals.
The camera is another major area of interest. Here it's an 8-megapixel shooter that can shoot 1080p HD video. For all you naysayers who were hoping the rumors of a 12-megapixel camera would pan out, bite your tongues. After all, the outdated assumption that the more megapixels you have the better simply isn't true.
