Grab your iPod nano and go — no accessories required. Or grab your iPod touch or iPhone 3GS or later, a pair of Nike+ shoes, and the Nike + iPod Sensor. Put the sensor in your Nike+ shoe — there’s a pocket for it under the insole. iPod touch and iPhone 3GS or later have built-in support for Nike + iPod, so no receiver is necessary. [source]
Now you can use your voice to use your iPhone. Just talk to Siri as you would to a person: “Do I need an umbrella?” or “Any great burgers around here?” or “Where’s the closest ATM?” Siri not only understands what you say, it knows what you mean.1 It figures out the right apps to use to find the right answer. Then, just like a personal assistant, it answers you. Siri makes phone calls, sends messages, schedules meetings, sets reminders, and more. How much more? Just ask, and Siri tells you that, too.
