Mobile solutions are essential to a strong IT infrastructure because they facilitate employee access to information in near-real time, regardless of location. Organizations that implement mobile solutions benefit from a work force that remains fully connected to the business both on and off site. This paper compares the Research In Motion BlackBerry solution (BlackBerry mobile devices and BlackBerry Enterprise Server) with the Microsoft® mobile solution (Microsoft Windows Mobile® and Microsoft Exchange Server 2007 SP1 with Microsoft ActiveSync® technology) by analyzing features of the user experience and the administrator experience. Use the information in this paper to understand the benefits and shortcomings of both solutions.
