Agree 100% with your comments Dan.
He's arguing the removal of Meego from their lpatforms because it can't serve all price points (and hardware spectrum) of the Nokia device base, but neither can WP7.
It certainly can't run on low end stuff, and sure as hell isn;t good enough to support the "top end" of town wrt devices.

If elop thinks Microsoft has an ecosystem in place because WP7 has Bing integrated and yo can pay to use x-box live on it, his concept of ecosystem is skewed indeed.
Methinks he uses the word to describe the idea of making profits in all areas related to mobile technology as opposed to an environment that meets the consumers wants and needs
then again, coming from a guy who used to work at a company that tried to describe bugs as product features, anything is possible....
