I'd say that the only OS that are actually important in terms of scale for the future are iOS, Android, Blackberry 10 (if it arrives before they go bust) and Windows 8 (if it arrives before Nokia go bust).
Ironic that Microsoft will make more money on each Android handset shipped than they will on each Nokia/Win8 handset shipped, but thats patents for you.
