That's the great thing about the internet; it serves as a permanent reminder of all those early mornings where I post something before coffee.
Oh, wait, we don't need antivirus, we're secure by design.
However, an expensive, resource-intensive security suite is /not/ necessary on Linux/FreeBSD (I believe largely due to better design and open source), and also generally not needed on Mac platforms.
Linux and FreeBSD are tools for serious power users. Yes, they're "harder." But you get a lot more bang for your buck.
Windows has a firewall, you're no longer an administrator by default as part of other changes from UAC, between XP and Vista, Microsoft put a lot more internal focus on security, Windows Update pushes itself on you, system file protection and validation stops key files being overwritten, IE8 has a phishing filter, popup blocker, more strict security settings, more process isolation/sandbox features. Outlook has unsafe attachment blocks.
Yes a full internet security suite will have some more benefits, but the main problems are still dodgy downloads and email attachments. If you know enough to stay away from those then the benefits of a full Norton/McAfee suite over Windows Firewall and Morro wont be enormous, I suspect.
Currently, there's no perfect solution to this problem. By making is very easy to run any software, you also make it very easy to run malicious software as well. App store/package managers provide half a solution, but are still far from ideal for vendors who don't want to rely on the whims of those packaging, and the process may not guarantee safety or security. Forcing applications to operate in a sandboxed environment is probably the way forward in the long-term, but that's still some way off due to the overheads required to do that while still retaining backwards compatibility with existing software. I think the fact we're in this limbo is one of the reasons that has made web apps popular, because it is essentially providing a sandboxed environment of sorts.
