Left out of the IOS7 club

The new IOS 7 system for iPhone was recently released, and it underwent a huge facelift from the last version. The apple default app icons such as music, messages, settings, etc. are all "flat" now, instead of rendered to appear multidimensional. Honestly, this is about as much as I can knowledgeably describe because although I do own an iPhone, it is of the 4th generation and is not totally compatible with the new update. As a designer, this might be an upsetting thing. I'm stuck with the "outdated" and older look and many of the processes in the new update have been streamlined for usability, etc. From what I have seen of the new design from friends' phones, it looks very clean and simple which I definitely appreciate. However, from a technology standpoint I really couldn't care less that I have the older version and the older now "dinosaur" phone that is not fully compatible with new updates. Everything works just fine - my phone hasn't died yet, it isn't particularly scratched or beat up, and the new improvements to technology since I got my phone, despite all the promises otherwise, are really not that revolutionary or innovative. The memory and battery life have gotten better, the cameras have been upgraded, the color has changed a bit, and the screen got taller. Thats about it. Thats all I found worthy of remembering off the top of my head anyways and none of that is particularly innovative. So thats that. My phone works just fine, and even though I'm a designer and naturally attracted to pretty things such as ios7, it is not enough to justify me getting an entirely new phone. The two year contract is up and I am "due" for an "upgrade," but that is according to the companies and not the actual user of the phone. How different would the cell phone industry be if the 2 year upgrade rule was not imposed? There would be less anticipation associated with purchasing a new phone after two years because it wouldn't be a special advertised milestone, it is just another day with a phone that likely works just fine.
