Generally speaking, I'm not a fan of the new Mac versus PC ad campaign from Apple, simply because I think they're ineffective ads. Justin "The Mac" Long comes off as smug and smarmy, while John "The PC" Hodgeman comes off as a loveable, long-suffering goof. Guess which persona the average geek can better relate to? That said, this particular commercial does ring true to me, as someone who has long dealt with the annoyance of configuring a personal firewall. Note that the Mac doesn't claim to be better in this ad--it's just a shot at typically crappy Microsoft security measures. That, any computer user can relate to.
