Is upgrading from iPhone 4 to iPhone 4S a good Idea?
I know there are lots of iPhone fans out there and they are willing to spend big amount of money to buy a new iPhone. Recently Apple launched the new iPhone 4S, with a little bit of upgrade, like the new A5 dual core processor, Siri voice assistant application which is very cool, plus new 8 MP camera. what ever upgrade they did is good but in my opinion not good enough to upgrade from iPhone 4 to 4S because they still have the same screen size a processor that is good enough to perform almost all the task that 4S can do may be a little slower but it will not stop you from doing any thing you want to do with your iPhone 4. If you want to buy the iPhone for the first time I suggest go for the 4S, but if you are an iPhone 4 user want to buy the new iPhone 4S then wait and think is it worth paying for few minor upgrades and extend your contract with cellphone companies, or would you like to wait for the iPhone 5 with more upgrade a bigger screen.
Finally like to say, its your money and your choice, but I believe spending huge money for something that is just little bit different from that you already have is not a good idea.
