yes, worth it, I did it, it is much thinner, lighter, bigger screen, faster internet, faster wifi with 5ghz. It is so thin that i am very much can't believe it. Camera is very good too. If you take a lot of photos, it can be very helpful. screen wise, it is bigger so that you can see movies with 16:9. It is a little bit better than 4s on battery, I can get two days out of 1 charge.
