what hardware features in a fridge can you not live without apart from "keeps inside cold & light comes on when I open the door" ?

Louis Rossmann has one. He loves it!

It has a large Android tablet in the front door, so it can show you ads – coming soon.

I don't know about "live without", but automatic defroster, crisper drawer, ice maker, water dispenser, alarm when the door isn't closed. being divided such that my food choices fit easily into the fridge (some people want to put a large wide pizza box directly into their fridge), power consumption.I dunno if you'd call looks a hardware feature, but it has to match the rest of the kitchen decor. The TV in the door isn't something I want at all though.

I may an idiot and haven't been in the market for new appliances for a while, but between an ice maker and a door alarm, how could you possibly require Internet acccess? Does it offer an app on your phone to operate the ice maker when you're not home?

travisgriggs said refrigerator manufacturers limited desired hardware features to models which had undesired network features. This was the last comment which mentioned network features.

delaminator asked what hardware features could not be lived without.

fragmede listed desired hardware features.

probably the ice maker or something. I bought new appliances a few months ago, and I made sure none of them had WiFi. I even paid £50 more for the washing machine that didn't have an app.
