Between the contents of Harry J Foxwell's presentation on Oracle Solaris, and OpenSolaris, available from http://www.eecis.udel.edu/~bmiller/DE-OSUG/Oracle-Sun.pdf, and the announcement by the OpenSolaris Foundation that it will dissolve if Oracle doesn't nominate a contact person by 15 August (announcement is at http://www.h-online.com/open/news/item/OpenSolaris-governing-board-threatens-dissolution-1037134.html), I've concluded that Oracle has conceded the front office, desktop, and the low end back office to Microsoft.
As to why Oracle wants to waste its two billion dollar acquisition of Sun is anybody's guess.

Update: The OpenSolaris Foundation resigned en masse on 23 August 2010.
