After using my iPhone 3GS for four and a half years it was time to upgrade to a new phone. There are many significant upgrades after 4 years of development, but I guess its the speed of the processor and the improved photographic features that really impress.
The camera is much better in terms of megapixels and sharpness plus it has a twin flash and many software options. Because of the fast processor the camera can take many successive shots per second and has a pretty amazing video slow motion capability. The feature that has really impressed me however is the 'PANO'. The ability to produce on-the-spot panoramas with ease. The technology Apple uses is quite stunning when you know how much time and effort it used to take with previous methods involving multiple exposures and Photoshop. Here are some examples...
