An new report from Osterman Research is claiming that 95% of Senior managers in North America use BlackBerry devices. The report also claims that 63% middle managers use BlackBerries as well.

The results are based on 76 messaging oriented decision-makers that responded to a survey commissioned by Zenprise, a Fremont, CA based BlackBerry and Exchange management company.

The report and the statistics turned out to be rather interesting,” said Ahmed Datoo, vice president of marketing at Zenprise. “What we’ve seen in terms of the pain of managing the infrastructure, to start off with, we wanted to have a better understanding of who are the people using mobile devices in the enterprises. It turns out that about 95 per cent of the people surveyed said senior managers use it.
