Is it too late to get the 6+? I am looking to return my S6 Edge for a 64 GB iPhone 6+, but I would have to pay about $70 more from my carrier (restocking and price difference), is it too late to get a 6+ for the MSRP of $850 (hands are tied, so cannot get a refund for the S6E.) Will the phone remain viable in the future with iOS9, or will we see substantial upgrades with iOS 9 that will be available on the 6S+ but not the 6+? Can we see multi-window on the 6+? How does the processor compare to the Octacore Exynos that the S6 offers? What about app refreshing and browser refreshing? Which color retains the best value for an iPhone? I am thinking about buying a Gold one or Space Black. How reliable is Apple Pay? I'll ask more questions if I can think of some later. Thanks for your time.
