For what I do, I don’t really need it any faster. Spent a few days out at a remote cabin for a Christmas and I was able to get work done with 4G LTE; rarely did I even use Wireless when stopped over at some friends for dinner. Of course, the bang for buck mentality, we all want to be getting the latest and greatest. For me, I think those days are over. I will only upgrade now when either Apple says my iPhone cannot work with the latest iOS version or the device dies. A friend of mine is still on an iPhone 5, its beat up, but sure as hell still keeps him productive.
