Nope, not received any at home or work. I guess I am lucky that my ISP bothers to scan their mail feeds.
At work we are almost 100% MS Windows (except for one OpenBSD box that runs as a bridge) and we haven't been had any issues. I spent the time to setup a filter on the traffic coming in and out of our Exchange 2003 server and placed it behind a smarthost running Postfix which provides another level of protection.
The ability to disable via GPO all the really risky Outlook features combined with a SUS server for automated critical updates and virus scanners on all the clients means I really don't lose much sleep over viruses, I think we have had only a handful of infected files in the last 3 years and they have just been cleaned and dropped in the central quarantine.
Don't get me wrong, I like Linux as much (if not more) than the next guy. However this is something of a random troll
<edit>
On a related note, IMO computer security is 90%+ common sense and good admin practices and relatively little to do with the OS (atleast on a Windows Vs Linux level). Just as some people run unpatched Windows machines with no virus protection plenty of people run linux boxes with every port under the sun open to the world, do everything as root and never apply security updates. *shrug*
