I just used iOS 7 on an iPhone 4S for the past 4 days while my new 5s was being shipped and I don't see what all the fuss is about. It definitely wasn't as smooth as my old iPhone 5 but I didn't really see any major issues with it.
 
You seem to love wasting money, can you waste some my way? 😉

Contrary to what you assume, I actually make money on my iPhones. I always get a subsidized upgrade when I upgrade my iPhone and then I sell my old one on eBay for twice the price I paid for it in the first place. It's foolish for me NOT to upgrade each year.
 
Everyone was crying for so much function for so many years. Now apple gave it to us and people complain.
