Do I need virus software for a Mac?

Apparently, the official answer from Apple is NO! I bet this makes Norton feel great. While I myself have never run any antivirus software on my Macintosh computer I always assumed that others did. Since I’ve never had any virus type symptoms and I know the UNIX base for OS X I always felt comfortable that my system would stay “healthy”..

Let us know in the comments if you use any antivirus software on your Mac… and if so, why? If not, why have you never felt the need to do so?
