My mine take-away from this article is something that I've always thought was key: When you're developing for other people, use the same hardware as them. I was at a fairly large financial firm in ~2004 that was rolling out a system to a large number of users. These users had impulse control issues, and were not allowed to use mice or keyboards (they would be torn off and thrown across the room). So the screens they used were touch screens. Inventory was shocked when I asked for one of the touchscreens to use as my second monitor. When launch time came around my parts of the UI were the only ones usable. Everyone else had built tiny tap targets that were easy to hit with a mouse, but impossible to fat-finger.
