This document provides an overview of a presentation on native mobile apps versus mobile web apps. It includes slides on why developers were fighting over the two approaches, Apple's announcement allowing third-party apps on the iPhone, and the surprise success of the iPhone App Store. It also discusses factors that contributed to the App Store's success like its openness, revenue split, and fewer restrictions compared to mobile carriers. The document debates questions around whether apps create platform lock-in, if app stores are essential to a platform's success, and challenges of developing for multiple mobile platforms. It suggests that HTML5 and WebKit may become the dominant mobile platform.
