Wrap Up
The iPhone 4S is definitely an improvement over its predecessor, bringing speed, Siri, and a camera that is the best in its class. For iPhone 3G and 3GS, low-end android, and feature-phone users, its definitely worth the upgrade. For everybody else, the iPhone release pattern has been set. It’s the three-step process of design (3G), improve (3GS), and redesign (4), which means a redesign is coming next year. If you can wait it out, go ahead. But what we learned this year is that upgrade may not come when expected(the iPhone 4 was released in June 2010, with the expectations of a new release in June 2011, which did not happen). But waiting may not be for you, and in that case, the iPhone 4S is your best bet, with the closest competitor being the Galaxy Nexus, the flagship Android device. The iPhone 4S is a quality device that carries software (Siri) that will become the norm in a few years. After using it for over a week, I can tell you that the iPhone 4S is a device that will impress you (camera), surprise you(Siri), and make a great phone, at least until the next iPhone gets released.
