In a recent interview, I was speaking of improving interfaces 100 milliseconds at a time. The manager of the UI team for this large organization with millions of users asked if users really cared about how long it took to accomplish a task. Of course they do!. As Jeff Raskin put it:

Anytime you make a system faster to use, easier to learn and less frustrating, there are psychological benefits to the individual user and bottom-line productivity benefits to the enterprise. There are also physical benefits: an interface that takes fewer keystrokes and less "mousing around" creates less repetitive stress injuries.
