I don't think I've seen a single person in any office using the calc on windows- anyone who needs to do simple calculations more than once a day has a physical calc on their desk- so much better and easier to use.
Meanwhile, my linux box has a dedicated macro to opening and closing SpeedCrunch, I also have br from the command line. Along with a numberpad input, there is literally no difference here from a desk calculator (which I still have, of course)
