This document discusses device-specific versus browser-based development from a business and marketing perspective. It notes that early web apps on the iPhone had decent traffic but were hard to monetize due to limitations like inability to use audio. The success of the App Store showed that native apps have advantages for discovery, performance, revenue generation and intellectual property value compared to HTML5 apps. However, HTML5 apps have advantages for cost, portability and rapid updates. A hybrid approach using tools like PhoneGap can provide portability and updates with easier prototyping compared to native development.
