" Why don't you scan the bar code of every item in your kitchen"
That's probably where the "checkout of the future" comes in. I've seen a demo of it somewhere, bar codes are supposed to go the way of the dodo, eventually RFID tags are supposed to take over for them. You simply fill up your cart, walk through an arch with a high speed RFID scanner in it and either hand over your money or your RFID credit/debit card is automatically scanned. If that comes to pass the "fridge of the future" would then have an RFID scanner in it, and when it noticed a code that was usually in your fridge was no longer there, it would notify you. While some of the features sound interesting, personally I don't intend to EVER hook up an important household appliance to a global network. I don't care how secure they say it is it WILL have flaws. I don't need some virus playing with my houses heat settings or playing porno/Viagra advertisements on my TV. In any case these "improvements" should be physically isolated from the base functions of the appliance, and if they aren't purchasers should at least be able to hardware disable them (by simply not plugging them in to the network or physically cutting the wi-fi)
