The document discusses trends in mobile learning around the world. While trends are similar globally, choices in technology and cultural significance vary across regions. Mobile networks now cover 90% of the world's population, but specific implementations differ - for example, some areas have expensive long contracts while others use micro-payments.

The key is designing content for mobile contexts and users' moments of need rather than formal classroom settings.
