You sound like my dad, who used to claim that power windows on an automobile were "just one more thing that can break".

Not to say I disagree with him, or you. An ice-maker is a convenience, especially for we absent-minded (a nice way of saying ADD) types. There are times I need a continuous supply of ice, such as family get-togethers (particularly in Summertime) and having four ice cube trays is insufficient to the task, I don't have the time to be stockpiling ice cubes the week ahead, and I don't like paying someone else to freeze water in a convenient form for me.

In a fridge/freezer that is reliable, an ice-maker is not going to be all that more prone to breaking than any other component. In a unit that is "meh" (like the noisy P.O.S. I bought from Sears) an ice-maker is definitely going to be extra headaches.
