What non-Domino users don't realize is that the genius of the Domino is not its ability to drill floating tenon mortises; it's the flip switch that allows you to widen the holes in increments. This means you don't have to mark ultra precisely. It's really hard to put into words how versatile and flexible this makes things. Domino is to tools as Rush is to music. You either get it and get it HARD, or it just seems like a lot of noise.
