Just wanted to add on that the down-votes probably come from people that take your comment as perpetuation of the argument that macs don't need AV, vs taking it at face value that its been your experience (and mine) with the OS. On the flip side, I have 4 infected mac's being flagged by webroot right now because the users downloaded and ran things like fake flash installers. So "every day" users do dumb things on macs and windows. For those user, the AV performance hit is worth it (to me) :)
