Futuretrotech: the slide rule watch

We don't need no stinkin' electronic calculator.
SPOT smart watches? Bah! We'll be kickin' it old skool style with a slide rule upon the wrist, thank you very much. Besides, $250 undercuts that smart watch by a long shot,
and no pesky monthly subscriptions to contend with. Torgoen sure gave us the goods on this one — it'll do the duty on all of our currency conversions as well as fill the gaping need for solutions to all of our time, distance and speed equations. So many! How have we lived til now?
