Maybe this will throw some proof to my opinions. From the wikipedia ......
The initial reception to the iPhone 4S was very favorable with many users being impressed with its Siri voice recognition and dictation software. However, with no drastic changes and few new features apparent, the unveiling of iPhone 4S failed to impress some critics.
Reuters suggests this could open new market opportunities for rivals. Shares of Samsung Electronics, HTC and Nokia gained on Wednesday after the 4S was announced, while Apple stock dipped sharply. However, later in the day Apple shares rebounded, ending at a 1% gain.  Analyst C. K. Lu of Gartner believes that Apple no longer has the leading edge and 4S will only sell due to brand loyalty, as fans were expecting an iPhone 5 with a thinner profile, bigger screen, and stronger features. Some of these same people also wanted a cheaper stripped down iPhone 4.
These are good sources. The announcement of the 4S and Samsung,HTC, Nokias stocks gained the same day. And Apple no longer has the leading edge and 4S will only sell due to brand loyalty because fans were expecting a Iphone5 bigger screen thinner profile and stronger features. This is from the experts.
