Slide rules are analog computers that we used to use for calculators before the microchip.
I just think they are cool, but I think they also help teach the concept of significant digits, which my daughter just learned in High School Chemistry. When you have to visually line up the dials, you quickly understand the futility of the 3rd significant digit and question the utility of the second (except under special circumstances).
The Japanese company Concise seems to be the only current manufacturer. At first, I was put off by the circular design, but quickly discovered that it's easier to use than the classic linear slide rule. It came with a vinyl slip case – it didn't take long for me to rip that.
Slide rules are also useful if you work in an environment that prohibits electronics.
I only tested this with my 300, but I assume all of their products have the same dimensions. If not, that's why slicers allow you to rescale models.
