Sliderules can be useful, if you're proficient, for performing repeated calculations where only one variable changes. You can slide the indicator along and produce a series of numbers quickly and easily. I have my grandfather's sliderule as a keepsake, and got fairly decent at using it a few years back. I've fallen out of practice now, so if I wanted to produce a series of numbers it'd be quicker for me to write a little python program than try to remember how to use the sliderule.
