Defragmentation off HDD, is it necessary?

I've been using PC's for a good many years. I am an enthusiast. I enjoy tinkering, upgrading, trying new devices, etc. I purchased my first Mac (MBP-13") about 3 months ago and am pleased with the performance. I have found the OS X quite intuitive. My question: In the PC world one finds themselves defragging the HDD periodically. I checked out the support page available at Apple>Support and learned, according to them that defragmentation of the HDD is not necessary on a MAC. What are the views of group members here at ehMac.ca?
