It took almost two decades for personal computers to be transformed from techie toy to ubiquitous corporate asset. Mobile devices such as smart phones and tablets are on a similar though much faster path, quickly supplanting the PC as the tool of choice for business workers. Worldwide sales of smart phones are expected to pass PC sales by 2012, according to Morgan Stanley. Meanwhile, Gartner expects 55 million tablets to be shipped in 2011, and 103 million in 2012.2 Along with device ubiquity is another change: the democratization of business intelligence. Once restricted to reports for upper managers that were out-of-date before they were even delivered, advanced self-service analytics is now spreading to a broad swath of workers.
