Chetan Sharma has taken over the Carnival of the Mobilists this week on this blog Always On Real-Time Access. As always, the carnival is diverse, entertaining and thought provoking, so head over and enjoy! The two posts that especially stood out for me personally this week were James Cooper's report on mobile Internet use in South Africa and C. Enrequie Ortiz's short enty on one click for effective use of bar codes and NFC.
