The Mobile Index provides a sophisticated, proprietary algorithm for scoring the top products and services in each of 60+ mobile and wireless categories based on four variables: 1) technology innovation, 2) management strength, 3) market acceptance and 4) financial strength. The Mobile Index service gives enterprises more information than other rating services since it considers four important variables that are then combined in a proprietary algorithm to best estimate the product's relative value compared to others in the same category. This edition of Mobile Index evaluates the four major smartphone platforms: Google Android, Apple iOS, Microsoft Windows Phone and RIM BlackBerry. This Mobile Index focuses on the major smartphones built using the Google Android OS. Note: This report is sold separately and is also provided to subscribers of the Mobile Insights Market Research Service.
