Not me. I updated to IOS 9 on the day it was available. And my 6 plus works great. I'll wait till the iPhone 7 to come out.
It's funny because of our contracts and whatnot a lot of people I meet are on either the 5, 6, 7 upgrades or the 5s, 6s, 7s cycles. My friend has the 5s and never got the 6, but is getting the 6s. For me I had the 5, now 6 plus and will wait for the 7 plus
