When I saw this thread I thought it was nuts but then I realized that while I had never named the machine, my 4 1/2 year-old already did. My son calls it simply, The Silver Box.
All I heard for nearly 2 weeks while the logicboard was being replaced was, "Daddy, where is the Silver Box?" "Daddy, when are we going to get the Silver Box back?"
BTW, every time he sees the side of the machine he asks, "Why did they put a fruit on the side of the Silver Box?" to which is 2 1/2 year-old brother says, "That's just silly!"
Welcome to my house 😉
