etops, I think it was pretty clear from Rainer's post that it was not supposed to be relied upon for a precise comparison to costs and margins for existing technologies so there is need to raise alarm.

I think the vast majority of those that looked at the post took the graph for what it was intended to be, just a visual aid to emphasize the point that Rainer had made in the text above.

Nothing more, nothing less.

To quote Rainer's post, "We know that POET has a decent manufacturing cost advantage over its competition. That means POET can offer its products at a lower price, while still maintaining nice margins and while POET's competition has little or no maneuvering room left."
