Craig Mod's mental models

Their wordsSpeed in software is probably the most valuable, least valued asset. To me, speedy software is the difference between an application smoothly integrating into your life, and one called upon with great reluctance.

Their wordsSpeed and reliability are often intuited hand-in-hand. Speed can be a good proxy for general engineering quality. If an application slows down on simple tasks, then it can mean the engineers aren’t obsessive detail sticklers.

Their wordsFast software is not always good software, but slow software is rarely able to rise to greatness. Fast software gives the user a chance to “meld” with its toolset. That is, not break flow.

Their wordsExcellent touch interfaces feel tactile. The best “touch interfaces,” in my opinion, are actual buttons, things with physicality, haptics. But on a screen, to feel tactile is to move without latency.
