The newly announced Windows Phone Samsung Focus S really is thin. In fact, the specs have it as 8.55mm. How does it compare it the current Focus? The current Focus is about 9.9mm. OK what about the king of design – the iPhone 4. That’s actually 9.3mm so the Focus S really is thin. I know we’re on the verge of a new iPhone but it seems like the Focus S is already lined up to compete in terms of size already. Well thickness at least. The Focus S rocks the iPhone in screen size at 4.3” but that’s an entirely different story.
