What is so good about the iphone 4 and iphone 5?

I have had a iphone 4 and just bought a iphone 5. I was wondering why everyone is going crazy about the iphone 5? The camera is better and it might be a little faster but other than that I wish I would have save my money and keep my iphone 4.Is there something I'm missing about the new phone? Does it do a lot more than then the 4?

No, there's no noticeable difference. Only the iPhone 5 screen is larger by about 13mm, meaning it fits one more row of icons on the home screen. It's lighter in weight too.

The only difference you'll be able to tell is the screen. Everything is much more sharp, and crisp.

Alot better hardware
