"Mobile phone handsets are significantly more versatile than the category name suggests. Enhanced phones enable calendars, address books, still photos and even basic driving directions. The smartphone segment - having adopted larger displays and mobile applications processors capable of consuming rich media content - continues to grow in importance relative to the other handset segments. At the same time, low-cost and ultra low-cost handsets are emerging to enable mobile voice services at all income levels."
