Apple is ahead of the curve -- this is coming to Windows as well, although perhaps through 3rd parties. About 2 years ago, my then employer was considered a "strategic" customer to one of the big security/AV vendors. They came in to give us their dog and pony show about the future of security, etc... which basically said that the current strategy of using AV to "blacklist" bad stuff is ineffective. (I asked the awkward question "So WTF am I paying for your ineffective AV product?") The only thing that makes me nervous about "Gatekeeper" is that it is Apple-controlled, and Apple is a mercurial vendor whom I don't really trust to do things that are in my interest. I'd be happier if I could trust other certifying authorities, which would mitigate the impact of Apple cutting of the oxygen to unsigned applications in the future.
