Here is an article describing the new State of New York law requiring wireless security measures be enabled. Starting in October, businesses will have to enable firewalls or disable the SSID and post signs telling users that they should have firewalls and other protective measures installed on their computers. I know that this is an outgrowth of the technology outpacing the average user's ability to understand it. There are still way to few people using updated anti-virus and spyware removal tools on their Windows PC after years and years of having it hammered down their throats. Of course, the firewall is a good idea for Mac users as well, but an absolute requirement for Windows users.
