Santa Claus is coming to town, and he's sporting a new iPhone 4S with Siri. Apple's newest ad for the iPhone 4S features none other than the man himself, using Siri to get directions to his sleigh's next destination, check the weather where he's headed, and access his naughty or nice list while he's on-the-go.

An iPhone seems like a good way to keep track of your 3.7 billion appointments, no? Check out the ad for yourself above, and tell us what you think in the comments!
