Apple again shows that it is a powerful player in the smartphone wars. It won't be for everyone, the call quality and reception vary if you don't use a case. The call quality is improved and it continues to deliver an excellent music and video experience.
The touch screen really works, intutive, easy to use menu, and through iTunes it got better and better over time without having to move away from your PC / Mac.
The fact that every other manufacturer since the release of the iPhone has been trying to copy it proves to me that it really is ahead of its time.
