摘要

In the not too distant future, the most important tool for a professional tradesman might not be his pipe wrench or power tool, but rather his smartphone. Some of the current mobile statistics are incredible. According to Gartner/Morgan Stanley, it is predicted that mobile will be the "first screen" for all Web usage sometime between 2013 and 2015, which means mobile devices will overtake PCs. And today there are more than 5.3 billion mobile subscriptions worldwide, according to the International Telecommunications Union, more than the combined penetration of PCs, landlines and TVs.
