"I would be perfectly happy with a five-year update cycle for my refrigerator"
And I am perfectly happy with the no-year update cycle on my very dumb and perfectly functional fridge, thank you.
As much as I can eventually understand the interest of a "smart" TV, I'm sorry but a fridge is never going to have the capability of automatically checking what is stored in it, so I fail to see the point.
And RFID is not going to tell me if the milk jug is half empty or almost full.
It's all a bloody waste of time and money.
