What are the main advantages of the 8 vs the 6S? If I upgraded I see that I would get more memory (64GB vs 32GB) and better battery life. I would lose the headphone port, but thats okay if I get better battery life. I am tempted to go and pay off the $272 remaining on my contract and get the iPhone 8, but maybe it would be wiser to wait. Cant afford the X so don't mention it and besides I prefer the home button and touch id.
