There are a couple of things that ring a bell here. No doubt the idea is very appealing. I would likely use a machine such as this myself. The first bell rang when there is a long drawn out explanation of a product. Keeping your attention by diverting to stories/examples just as the answer is around the corner. It is a selling tool played by many advertisers out there. Secondly, most any machine has it's limitations. In this case, you can see that the wood being cut or shaped is rather thin. This is due to the cutting depth of the router bit being used. So if you decide that you want to build a speaker cabinet with walls that are 1" deep, you will be laminating multiple panels of the same cut Exactly, one on top of the other. That isn't necessarily a bad thing. In fact, It can provide added strength to the panel being made. Just realize that it is a multiple step process. Next is that the router bit being used doesn't last forever. In fact, the smaller the diameter of the bit, the faster it dulls. Even a 1" diameter bit will start burning due to dullness in a few feet of cutting a deep groove. And I do mean that the fatter bit will be making multiple passes to cut that groove to the desired depth.
I am not saying that a machine such as this doesn't have it's place, as long as the limitations are considered against the desired projects to be made.
