Convenience to Consumption to Quality
This rush to use the phone as a camera has meant that phone makers are keen to improve their product (so as to compete effectively with it against each other) and as a consequence they overtake the incumbent camera makers in quality as well as quantity.
The same phenomenon was experienced by fixed component “Hi-Fi” audio products. The quality of mobile music was poor but it was convenient and convenience translated into consumption and consumption translated into quality improvement and eventually the evaporation of usage of the traditional category.
—Horace Dediu, Competing effectively against your most potent competitor
