MG Siegler:

That’s the thing — when people say they’re disappointed about the new iPhone, what they’re really saying is that they’re disappointed it doesn’t look that much different from previous version(s). But again, not only is that true, Apple went out of their way to make sure that was the case. [...]

Apple is not and will not make changes just for the sake of change. And while some may now be clamoring for this change, the paradox is that if Apple did make some big changes, many of the same people would bitch and moan about them. Apple is smart enough to know that in this case, most people don’t really want change, they just think that they do because that’s the easiest way to perceive value: visual newness.

Perfectly said.
