Whqat is the difference between an Iphone 4s and Iphone 5. For a layman?

I want to buy the 64 gb version. So i get 64 gb in both versions. But what is better about an Iphone 5?

Please don't be technical. I'm not phone talk savvy

Added (1). If i have a budget problem, then are the advantages in 5 worth the higher price. Because i've bveen told that the advantages are mainly cosmetic, and the higher speed and camera are great, but the 4s is fast enough with a good camera.

So would you pay more, if you had a budget?

Well simply put, faster, lighter, more powerful with a bigger display. That's about it.

Here are the differences between these brand new IPhones
