The market for improving desktop UX is potentially huge, impacting billions of users globally. While a full overhaul is complex, an MVP exploring novel interaction models or interfaces is feasible within 2-4 weeks. The competition is somewhat established with OS providers and specific app developers, but there's room for innovation in exploring entirely new UX paradigms. Desktop UX concepts can be localized relatively easily, as user interaction principles are often universal, with minor adaptations for language and cultural norms.
