Comparing SQL Server 2005 and Oracle

A few interesting whitepapers comparing SQL Server 2005 to Oracle (and particularly the use of RAC) have just been posted here

On a slightly different note (non-SQL Server), I am disappointed that PDF support is being pulled from Office 2007. I've been using this a lot in Beta 2 however I hear it might be included as a free download but not sure yet.  Brian has a good post about the reasons for removing PDF support This is Adobe's official response
