The weight saved will vary pretty widely depending on the tire size and the number of spare tubes. Also it will vary if you compare regular butyl tubes or light weight ones. Someone running 25mm tires, light butyls tubes, and one spare might save 3 or 4 ounces. Someone with 2" tires, and 3 regular butyl spare tubes, may save close to 2 pounds. But, yeah, it is in the realm of personal choice and certainly not a slam dunk given the cost.
