I just got my iPhone 3G S up and running and am blown away because as a power user - even using the new OS 3.0 on an iPhone 3G I had to wait 5 or more seconds for an email address to resolve. Multiply this by 100 times a day and you can imagine the frustration. I also was not satisfied with the browsing speed of the 3G with the 3.0 upgrade. The new S model is blazing fast compared to its predecessor. It is highly recommended.

But if you want to know what the most important feature of the 3G S is, it could very well be video. You see this phone is not the first to shoot video but it does shoot great quality video and possesses a screen allowing an enjoyable playback experience.
If you track the rise of social networking the natural evolution of sharing everything via photos, video snippets and text is to share all aspects of your life via video in real-time. Also this will be done from multiple points of view. So I will be able to watch what happens to the left and right of people I track at all times. I realize how ludicrous this sounds but I don't care - I know it will happen. Oh, and the archives will be available forever as well. Data center owners must be salivating.
The iPhone 3G S which has video quality which rivals standalone video recorders could be one of the catalysts which moves us into this new world of always-on mobile social video. For more on the ramifications of video on the iPhone 3G S check out this article from Todd Krieger.
