As a feature in a phone that is already simple enough to use by absolutely anyone, this is probably a great addition.

Making things too simple is still a bit of a problem because it does not force people to learn even the basics of anything. The computer illiterate duck is mostly based on real stories, unfortunately.

Heh, since already some "analysts" have been claiming phones with any physical buttons on them are way outdated, I suppose soon we will all be issuing speech commands to an iPhone Shuffle.
