LOL, I like this thread!
On a serious note, I think people are over estimating things. People won't be talking to fridges. Think about it.
There will be one of those "Mira"'s (or a tablet PC on a wall! ;-)) connected up via 802.11b probably (or something newer no doubt) to things like fridges, clocks and kettles. So in the morning you can get up and go to your Mira thingy, where its also part PDA, and you can press a button and your kettle will turn on, the fridge will inform you that your low on milk and adds it to your shopping list online and the clock syncs with BT's time server online as everyone will have a broadband connection. You can then take your PDA from another wireless connection to your Mira and it has your shopping list, emails, To do and other stuff all done automatically. It will also remind you 10 mins after the kettle has boiled that you will need to refil it and that your electricity bill has been taken from your bank account.
Sounds good to me!
Thanks,
