This is exactly why I own the Nexus S 4G, as I stated when I first bought the phone. My recent article about using the Nexus S 4G alongside the iPhone 4S drew a lot of comments from those claiming it to be unfair that I would compare the latest iPhone to an "old" phone like the Nexus S. The fact is this old phone is still the current flagship Android phone until the Galaxy Nexus is released next month, and as such it gets every major Android release that comes along.
So while millions of Android owners have now entered the waiting game for Android 4.0, my old phone should see it before too long. That is exciting as ICS looks nice from what I have seen of it.
