North American business customers spend 23% more on mobile services than consumers do. But until now, mobile productivity application development has lagged behind mobile entertainment services development, limiting the opportunities for serving the business customer. That is now starting to change and by 2012, driven by mobile productivity applications, data services will account for more than one third of North American business?s mobile services spending. Data services will gradually become a larger share of wallet for the business customer, equaling 34% in North America by 2012, ABI Research says.
