The Apple iPhone 4S came out yesterday with what has become a customary level of media fanfare. One worthy feature, while not exactly groundbreaking, is still very cool. It's the voice-controlled organizer and assistant, known as Siri.

As Macworld's Jason Snell explains, the voice command comprehension and application is far from perfect, but Apple's not claiming that it is.

As Snell shows us, being able to talk to your phone and get things done can be very handy, but Siri just can't understand your intentions nearly as well as a person can.

That being said, Siri still seems to be a useful tool, and as long as you've got your iPhone, you'll always have someone to talk to.
