I know what you mean! My sewing machine is still flexible enough to do what I want, but like a couple others here, I don't like my washing machine, because it can only be run with their pre-set programs which don't always do what I want.
Maybe it's a sign of me getting older, but I feel like most appliances don't gain much by being hooked up to the internet. I don't need my fridge telling me when I'm out of milk - that really doesn't improve my life in any significant way - and it's a security and privacy nightmare.
