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 did an OTA firmware on my car yesterday which took three hours during which time it was not usable and even the alarm was disabled. It also woke me up this morning by messaging me to tell me it was fully charged. Another feature is that it provides its own WiFi hotspot for up to 8 devices to use. OTOH it seems to be incapable of playing a list of MP3s in random order unlike the old car.
