An inflection point is where progress starts to decelerate ahead of a possible
reversal in direction.

An inflection point is the point where a function changes sign. This can be
both a positive or a negative indication.

This article carries a positive tone, so what they probably mean is that ICS
to Android is the point where people start saying more positive than negative
stuff about Android.

~~~
sixbrx
No it's where the _second derivative_ changes sign. You can think of the first
derivative as the motion, and the second derivative as the "force" that's
driving the motion - the force is changing direction.

~~~
starwed
Equivalently it is where the second derivative is equal to zero -- which
implies the first derivative is at a local extrema.

In the context here, it's clear that the inflection point would be the point
of greatest change.

~~~
sixbrx
Well not quite equivalent exactly - the second derivative could just touch
zero and then go back whence it came :) That wouldn't be an inflection point I
think, I'm not sure what you'd call that...
