The document discusses trends in the mobile industry for 2013. It notes that as of 2012, there were over 2.5 billion people online globally, accounting for about 35% of the global population. Mobile traffic already accounts for 15% of total internet traffic and is growing quickly. Device sales, especially smartphones and tablets, are pushing more people onto the mobile internet as PC shipments declined in 2012. Tablets are poised for a large increase in sales in 2013, though their adoption has so far been highest among wealthier and older users due to lack of carrier subsidies.
