I'm upgrading from the 5S to the 6s+ with an expected delivery date of 10/14. Previously I had the 4S. It's funny because the 4S and 5S are the best selling phones in Apple history and so far as the best longevity. I feel like the new series phones are only for trial purposes whereas the S series it's perfected. I mean the 6S has Force Touch! The 5S had a finger print sensor and twice the speed. The next phone I get of course will be the 7S or whatever they call it. I will not be guinea pig for the 7. Now everyone is wanting the 6S! It just cooler I guess. Anyone else on the same upgrade path?
