This graph is an exclamation point to our earlier discussions about successful companies coasting, and particularly your dire predictions, Dad, about the iPhone’s future.

First, notice RIM’s tanking market share. They’ve been trying to stay relevant with the Storm (and rapidly iterating on the platform to produce the Storm 2 a year later), but it just ain’t working. Blackberries are still very much a cell phone for Suits. You don’t buy one, you get chained to one.

Ditto Windows Mobile.

But the impending confluence of the “Android” and “iPhone” lines on the graph should give us all pause.
