Apple’s new Siri ad: Remind me to do WHAT again?

Would that the iPhone’s intelligent assistant were as smart as the latest TV ad suggests

Based on my experience with the iPhone 4S, Apple (AAPL) is doing something very un-Applelike in its TV ads for Siri — over-promise and under-deliver.

Case in point: The last instruction the woman gives her voice-activated assistant in the TV ad that debuted Thursday night. “Remind me to do this again,” she tells Siri on a beach in Santa Cruz at the end of what appears to have been a lovely computer-assisted cross-country road trip.

Your mileage may vary, but my Siri would have no clue what was meant by “this.”
