Seems accurate to me. :-) In my experience email viruses can't spread
the Windows way because (for one reason) attachments can't execute
without the user saving the file, and then changing the permissions to
executable, and then launching it. Too much hoop-jumping to get the
thing to spread. I'm sure there are exceptions, but in general I think
that's why we haven't seen many Linux based email viruses (I haven't
seen any).
As far as being intruder safe, how about this weblog commenting on the
Honeynet Project?

"Recent data from our honeynet sensor grid reveals that the average life
expectancy to compromise for an unpatched Linux system has increased
from 72 hours to 3 months."
So, it appears as if some Linux based distributions (SuSE and RedHat in
that report) are getting more secure "out of the box", even as they
gain in popularity.
