A fridge is a fridge, the basic mechanical working principle of it didn’t change over the past 40 years. But people have a lot more expectations put into what a fridge should be able to do nowadays, and electronics or complex mechanism such as the ice maker is generally the first to break on a modern fridge.
The moral of the story is, don’t buy a fridge with an icemaker or have a tablet attached to it, and you should be fine.
