Food Fascination apart I would see such technology has many more applications which can make life easier for the physically challenged. For example if the room furniture is equipped with such communicating capability it can tell a blind person about its presence as soon as the person is near it. A person who has paralyzed legs could operate the lawn mower , a washing machine or a dishwasher while sitting on his wheel chair in the drawing room. Instead of making the healthier people coach-potatoes such technology may better be used to make the life better for these physically challenged people
This is a fascinating concept, especially for backyard barbeques and for holiday dinners. In both cases, it is very easy (and common) for the cook to become distracted and then you are suddenly in the mode of attempting to rescue dinner.
Insofar as iVacuum cleaner, recall that we already have iRobot which, in fact, works very well and with the number of models available, it is a fairly simple matter to choose the one that best suits your situation (and the cat tends to keep away from it).
I don't think most of us would trust our faces to iShaver, but iPotato peeler certainly has some potential for helping prepare dinner.
Did you know that Dweezil Zappa co-hosted a cooking show on The Food Network? Hum. Anyway, I think this invention actually quite something and to me points out that "computing anywhere" is really taking shape - for today it's the shape of a rump roast but soon....
What's next? An iGriller that contains a Peltier cooler to keep your steak cold all day long, then switch to grill mode when you remotely tell it to while texting in traffic on the way home.
The iVacuum cleaner is a good idea. Give it a webcam, propelled wheels and steering, and you can do your housecleaning from work when the boss is not looking. Try not to run over the cat.
An iLawnmower is not such a good idea, but someone will hype it sooner or later. Some marketeers have way too much time on their hands.
