Apple posted their new TV spots on their website, including the one regarding Mac's immunity to viruses.

Thought I'd post a couple corrections to my previous post.

First, Mac Guy isn't wearing a suit, he's just a laid back dude. Second, if you pay attention to the verbeage, you'll note that it doesn't actually claim immunity - it just points out that there were over 114,000 viruses for PC last year, not mac, and that Mac Guy won't catch PC Guy's virus. While this is probably true, I still stand by my original opinion that this was a horrendous move on Apple's part. The TV spot is clearly designed to hype OS X's immunity to such ailments, and that's going to come back to bite them in the ass as soon as someone releases something into the wild that makes you lose your data.

Using a Mac doesn't make your data secure. It probably makes it more secure than it would be on a Windows box - simply due to differing architectures and out of the box configurations - but regardless of your platform of choice, you must be aware of the threats and be proactive about them in order to avoid problems later.

They have a few more commercials, most of which are pretty funny - in particular the one about restarting. In the years I've been using a Mac, I've only ever had to restart one due to a crash about a half-dozen times. Many of those crashes were caused by me overrunning a graphics buffer while doing poorly thought out work in my Computer Graphics course back in the day, and only maybe two due to unexplainable circumstances.

It's worth noting further than when the Mac does crash, it does so in a manner that does not terrify... a simple message is displayed with a transparent background stating that something unexpected happened, and you must restart your computer; whereas Windows prompts you with the BSoD filled with hex code, memory addresses, and other data that might be relevant to the crash, but which no user would ever find informative.
