I think you miss my point. I'm not suggesting that MS should or will consider a unix port. I'm making the point about what may have been had MS & Sybase maintained their partnership which offered both a Windows & Unix based product. Combined together as they were, they would almost certainly have had an even greater share of todays market. MS may be very single minded about Windows, but the rest of the world is not. There is a huge market out there who will not use Windows as a host platform for servers, and MS chose to turn their back on that market. For a company so obviously focused on their own success, that is a strange business decision to have made.
