"With the introduction of the iPhone in 2007, Apple has clearly differentiated itself from the competition in areas that are most important to business smartphone users," said Kirk Parsons, senior director of wireless services for JD Power and Associates.

One quarter of smartphone users reported that they had experienced at least one software-related issue with their handsets.
Among that group, 44 percent said they had to reboot their phone at least once a week, and 34 percent reported applications would freeze or otherwise malfunction at least once a week.
Clearly there's no room for complacency on the part of smartphone makers or software developers.
