A lack of imagination on my part perhaps, but I can't think of anything I'd use it for which isn't either: 1) cheating myself and others of leisure (e.g. I suppose I could use it to fake-keep up with friends..? Or plan a holiday and book a load of stuff for me. But I like doing that!), 2) not feasible (loading and unloading the dishwasher, which is already the robot I used to wash dishes), 3) utterly insane (it's tax time in the US).
