I want to make a rather bold statement here (though that isn't unusual). This morning, I was reading some of my usual tech news sites, which included reports of malware, Windows woes, and the usual litany of issues plaguing various platforms.
And then it dawned on me ... just who the ideal candidate for Linux should be. It's not the developer (though they probably get more benefit out of the platform than any user type), it's not the gamer, it's not the geek, and it's not the administrator. The ideal candidate is the average user.
