Hey Dakka I need your help! Me and the old ball and chain have been putting some money aside and with the phone plan we're on we can upgrade to an iPhone. Now this doesn't affect me at all as I can survive with my nice little Nokia prepay

but for whatever reason the wife says she NEEDS an iPhone and so we decided she would get it.
Now the question I pose is what is better between the 4s and the 5?
The important things we want to know are things like:
Processing speed? Does the 5 run that much faster than the 4s or is the difference negligible?
Camera quality?
What are the new features the 5 offers the 4s doesn't?
Basically I need to know anything that would make one phone better than the other and I don't mean just what the ads say, I'm hoping for more like people's personal opinions on them. I really hope you can help Dakka!
