375 Million Use Consumer Cloud, 500 Million be End of 2012

Some 375 million consumer were using some form of cloud service earlier in 2012, while perhaps 500 million will be jumping to an estimated 625 million in 2013 and then doubling over the course of four years to reach 1.3 billion by 2017,  according to IHS iSuppli. 

So many use cloud services because many cloud services are provided at no incremental charge to end users, or cost very little.
