One of the biggest attractions of the iPhone 4S was the Siri personal assistant, an app which received a lot of attention from users and analysts. While this is not a new technology, it took the release of the dual core processor to make the constant use of such a program feasible. Since voice recognition does require a bit of computing power, the former processor available on Iphone smartphones were not capable to run it constantly. The latest one, the A5, does have sufficient power, so Siri is now available to all owners of the 4S.
Since the Apple way of doing things is so focused on the usability and less on specs and performances, Siri is actually quite representative of their way of doing things. Giving the user something that makes his life easier and making it one of the main features of a new iPhone is a nice move on their part. It’s definitely something that iPhone 4S users can show off with in front of their friends. The special thing about Siri is that you can talk with it and ask it questions and it will understand what you want and it will formulate an answer for you. By speaking to the phone you can make it do something or you can receive information that you need. The intelligent algorithm included on the iPhone 4S will understand a question and the logic behind it, so it’s able to give you an answer. One example is asking Siri if an umbrella will be needed on Friday. Siri understands from your question that you need to know what the weather will be like so it finds out for you and it gives you a reply to your question. When you think of the computing power required for something like this, you will understand why a dual core processor was needed before Siri became possible.
