Apple really needs to step it up with the next iPhone and IOS because the OS is really looking dated. In fact, it looks exactly the same as it did in 2007 on my first iPhone.
I must admit to being at a loss why some people seem to think that the appearance of IOS is so vital in it's operation! Surely the most important factor is what the OS actually does. A well thought out and designed item doesn't have to have its appearance continually changed to make it better! The stability of the IOS design is the main reason for my staying with the iPhone. I know exactly where everything is and what it's going to do.
When I bought my iPhone 5, within minutes I had set it up and installed all my data etc from my old iPhone and the new one was up and running. In comparison, my son spent more than an evening transferring "most" of his data from his "old" Galaxy 2 to his new Galaxy 3!
'Nuff said!
