Consider the human factor solution that states it is better to change the machine than to try to change the human to accommodate the machine. Are there machines (or systems) that you use in your daily life that still have room for improvement? Are the current generations of Windows PC and Apple Mac as usable as they might be? If not, what improvements can you suggest? Is the World Wide Web as usable as it might be? If not, what improvements would help? Are we just beginning to see some breakthroughs in usability, or have most of the big improvements already been made?
