Mobile Computing: The Next Platform Rivalry
分析移动平台为何在治理模式上存在差异，提出“层级”概念解释其优势与局限，并用近年主要平台赞助商的不同做法加以说明。
Competition to become one of several dominant mobile platforms is intense. Platforms compete for developers, who create applications which make the platform valuable for users. Why doesn't one form of platform governance emerge as superior? This essay will stress the reasons for differentiation and proposes a new argument linked to a platform's “hierarchy.” Hierarchical governance features can help at one moment but then get in the way at a later time. These arguments are illustrated by different approaches to platform governance taken by the major mobile platform sponsors of recent years.
