If it could save a person's life, would you find a way to make it faster? "If it could save a person's life, would you find a way to shave ten seconds off the boot time?" [Jobs] asked. Kenyon allowed that he probably could. Jobs went to a whiteboard and showed that if there were five million people using the Max, and it took ten seconds extra to turn it on every day, that added up to three hundred million or so hours per year that people would save, which was the equivalent of at least one hundred lifetimes saved per year. "Larry was suitably impressed, and a few weeks later he came back and it booted up twenty-eight seconds faster," Atkinson recalled. "Steve had a way of motivating by looking at the bigger picture."

Unobtrusive feedback An Article by Jeremy Keith adactio.com The text 'added' and 'removed' drifts upwards from the toggle button and fades away. So we all know Super Mario, right? And if you think about when you’re collecting coins in Super Mario, it doesn’t stop the game and pop up an alert dialogue and say, “You have just collected ten points, OK, Cancel”, right? It just does it. It does it in the background, but it does provide you with a feedback mechanism. The feedback you get in Super Mario is about the number of points you’ve just gained. When you collect an item that gives you more points, the number of points you’ve gained appears where the item was …and then drifts upwards as it disappears. It’s unobtrusive enough that it won’t distract you from the gameplay you’re concentrating on but it gives you the reassurance that, yes, you have just gained points. uxinterfaces
