My parents got a fridge with an ice maker years ago when they put their new kitchen. I always thought the ice tasted funny. Even with cleaning the freezer every so often, it still tasted like freezer to me. It sounds like they're different now with filters and what not, so maybe freezer flavored ice is not a problem anymore. My mom ended up disabling the function so she could have more room in the freezer.
I opted not to get one with an ice maker or water dispenser when my husband and I redid our kitchen. I do fill ice cube trays, but I keep a ziplock covered container that I dump the ice cubes in. The ice always tastes good. No freezer taste. I can wash the trays and container every so often to keep everything disinfected. Maybe it's a little more work, but that's what I like personally. If I'm entertaining a bunch of people, I find it easier to get a bag of ice anyway.
