What the!?!

I just saw a commercial for "Personal Trainer: Cooking", whereby some kind of Garmin-esque electronic device (it turns out its a Nintendo of some sort) will speak cooking directions for you while you cook. Its website says: "focus on the food while you cook thanks to Hands-Free Voice Control" alternatively, you could focus on the food while you cook by reading a recipe in advance! The website also notes that this is the first in a series of "Personal Trainer" software. Coming soon are "Personal Trainer: Math" and "Personal Trainer: Walking" Walking? Focus on your feet while you walk thanks to Hands-Free Voice Control! Do we really need a little machine giving us verbal directions on how to walk?
