It has little, if anything, to do with users. The basic security 
implementation of the filesystem, kernel, permissions and the modularity of 
GNU software is what is behind the inability of a virus to infect a GNU/Linux 
box or then to either do any damage or spread further.

It's not just the heterogeneous nature of the software, although that 
certainly has an impact, it is the fundamental design of the components.

Simplest analogy is of a school playground bully.  He's going to pick on
the first year kids smaller than himself, not the final year students
who belong to the school judo team, who would probably hand him his
teeth in a hat.

Virus writers pick on Windows because writing a virus for Windows is trivial. 
Writing a virus for GNU/Linux is hard.

It's not about the users, it's about the system.

The other reason (yes OK... "Nobody expects the Spanish Inquisition!"
etc) is that quite simply Windows gives MUCH more opportunity for it,

Yes, but not for the reasons you mention.

The main reason is the tight integration of IE in the OS. IE, being also 
tightly integrated into the default email client, provides ready access to 
the privileged areas of the system that an email should NEVER be able to 
reach. Instead, ActiveX, VB, pif, bat, scr, any number of formats in an email 
can infect a Windows system. Windows should simply not run arbitrary 
executables with system privileges - you cannot do that on GNU/Linux, you can 
still on Windows because it keeps thunking down to insecure MS-DOS 16bit real 
mode code.

The fault isn't in the user for not reading the warning, the fault is that the 
system doesn't do enough to prevent such a warning becoming necessary.
