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.
