It sounds like some of y'all are dogging the 8 just to justify getting the X.
Look at years past. When has an annual upgrade really been THAT impressive that someone HAS to get the next model? Small spec bumps. A larger screen from 4S to 5 then 5s to 6.
I've had my 6 for 2.5 years and really, I see no reason to really upgrade at all, other than just having that itch. The smartphone market has plateaued and matured, I believe, to the point where manufacturers can't add much value to the next model. Sure, little better camera, better speakers, better screen, but nothin like Touch ID or Retina display.
