There are plenty of fridges that don't incorporate "smart" features. There's nothing really complicated about a giant box that you put food in to keep cold and maybe an integrated water dispenser.

I've been shopping for a new fridge lately, and from what I gather most "smart" fridges are still extremely expensive and that makes "non-smart" fridges still very desirable. In other words, "smart" features may not be new, but they aren't standard on a typical fridge... yet.
