I'm currently using an iPhone X. It's fine, don't love it. I have the chance to pick up a brand new 8+ for $600 (which I would probably use for a few months until I could get the newer 6.5" X+). Assuming I can sell my X for $800 now and being that the the new devices won't have any sort of home button will there be any sort of market for an 8+ in a few months. If I pocket $200 now, will I be able to get $400 for my 8+ later on? Am I better off handing on to the X? Thoughts?
