USABILITY VS DESIRABILITY IN MOBILE UX

Summary from the TLDR Design newsletter

Usability and desirability are two distinct levels in UX design, with usability serving as the foundational requirement for an easy, intuitive product experience. Desirability goes beyond usability by solving the right problem and creating an emotional appeal that separates market leaders from competitors. While usability ensures functionality, desirability makes products memorable, recommendable, and commands premium pricing in the marketplace.
