I never expected this phone to make my life fulfilling. I just wanted a new iPhone and figured the X would be a great replacement for my 6. It has. Life is fantastic for other reasons. Mainly from my positive interactions with real people.
That's also a substantial upgrade from your iPhone 6 to the iPhone X. Completely new technology with a new display and form factor, I'm assuming you will be content for quite some time with the X. Especially for those who are Tech enthusiasts.
