But that's easy Michael
It saves you having to do it. Just like Face Book and Twitter allow you to tell the world the colour of your underwear and the size of the last dump that you had.
Your Fridge will be able to reorder replacments for what's gone off while remaining unused and your Toaster will be capable of ordering bread when it feels the need or after making so many slices of Toast. After all a Smart Toaster was designed and exists to be Smart and save you time with the Mundane things that so many people can not be bothered with.
Also you'll have no security at all so it increases Good Behaviour as all your wrong doings will be on Public Display for all to see so you'll not do anything wrong. Just like that guy from Face Book tells you that his offering is good because it encourages you to not do anything wrong.
When you are Perfect you have no need to worry about anything bad happening to you as those Nasty Bad People will avoid you like the Plague and go after the easier targets. Honest. Its also better if you dont think about things like this as it taxes your brain too much so just leave it to your Fridge to keep enough food in the house to keep you feed.
Of course when your Talking Toaster starts to annoy you because it continually wants to cook you some toast you can resort to the Analog Baseball Bat and smash it up completely, but then you would have to remember to order your bread so you can have some toast. [/Magical Laughter]
