Well, now that the X is here, to overwhelmingly positive reviews, and some negative and or nit picky ones, I assume that Apple would change the design on a more frequent timeline. I wouldn't be surprised if it's yearly, 1.5yrs or even the old 2yr design change. Coming off of this article from 9to5Mac https://9to5mac.com/2017/11/09/jony-ive-iphone-x-interview/ Johnny Ive said that next years iPhone will do things that this years X can't. Of course it's the same since the original iPhone and the yearly updates, but a fingerprint under the glass could be a game changer as well as a slew of other things. I assume the OLED version will continue to use the X to differentiate from the normal. IMHO enjoy your device. Something bigger and better will always come out. There's always going to be the debate on whether or not you should get this version or wait for the next. Usually the second iteration of a new device is probably the best bet. That's why I waited until the first refresh of the newest MacBook Pro line. However, with the iPhone, I plan to upgrade whenever I feel it is necessary. Anyone enjoying their new X like me? Or are you having buyers remorse, and plan to return and wait for the next years version?
