*sigh* Once again, remove yourself from the equation and think larger (and different).
Music doesn't scare people. It excites them and makes them want to sing and dance. People automatically love music. So with a music device, it's easy to go for the excitement factor. In fact, you want to pump that up to make your device look more exciting then any other music-playing device. With a device that lets you converse with people over a distance, that too, doesn't scare people. It's exciting, it's moving, it's very human.
But most people (unlike say you, me and most other tech lovers here) are scared of talking devices. Both experience and fiction (movies) have made them scared of them. The robot voice is weird (not pleasant like music), and talking to a device rather than to a person seems wrong. So the last thing this commercial should do is try to generate excitement (and exactly how would it do that, by the way, with a device that you're supposed to use to say, "remind me to buy milk"? Should the person be dancing in silhouette while they say it?

).
To sell a device that talks, an ad must avoid the voice of the machine (mechanical and off-putting), and make it seem useful, practical and friendly--and human. This the ad does that. Anything else and it chances scaring off its customers rather than luring them in. This isn't, like the iPod, a device that, if someone dances with it, mobs will pour in saying, "gimme, gimme, gimme!" This is a device with a robotic voice that makes people hesitate. The ad has to (metaphorically speaking), get down to the scared person's level, pet the phone and say, "See. Nice device. It won't hurt you...."
Later on, when everyone is used to it and it does't seem so strange or scary, THEN they can make an ad that generates excitement.
