It is a little gimmicky, but it's also a tool like any other.
We have a few customers who work with things like leather, where the material shape is not consistent. One in particular makes boots and belt buckles, and his wife makes jewelry, so the camera is extremely useful for them - He lays out the boot sections first, then the buckles, and then she goes after him, filling in the left over spaces with earrings, bracelets, etc. With the camera they can maximize the material use much more easily than they could before.
We also have a lot of folks using the system in schools, and there it's awesome - kids draw something with a sharpie, capture it, use the trace feature, then engrave it onto a cookie, their notebook, or even their phone case. It's a simple way to design something, it's quick, and it's a great "direct" kind of exposure to how powerful the tech is. Yes, it's a bit silly, but they don't seem to care.
