My washing machine doesn’t need Wi-Fi.
It's a feature that I would regret.
I just need a way to wash my pants.
Not show them to the Internet.

My oven doesn't need Wi-Fi.
I'd value that least of all.
It's already shielded from getting too hot.
It doesn't need another firewall.

My fridge does not need Wi-Fi.
That is just not useful for me.
I want a place to chill my food.
Not chat via TCP/IP.

@neil I also don't understand the urge to connect all devices to the internet. Even your toothbrush. I guess I'm just an analogue old man :)
