My productivity isn't so much enhanced. It's only 1%... 2%... 5%... globally, for each employee.

Have you ever dabbled with, mucked around in, a command line? Autocomplete functions there save millions of man-hour-typing-units per year. Something to think about.

A single employee, in a single task, for a single location may not equal much gained productivity, but companies now think on much larger scales than a single office location.

Work gets scheduled on short time frames. 5% savings isn't enough to change the schedule for any one person. At most, it gives me time to grab an extra coffee. I can't string together "foregone extra coffees" into "more tasks/days in the schedule".

Now making a kettle faster? That might actually be something.
