A few years back we removed all desktops and gave everyone laptops. This was to allow for greater mobility and agility of our workforce and to increase their quality of life. Our workers can go home and have dinner with their families, then continue to burn the midnight oil.d
Our group travels constantly. Having the 3G and EDGE cards has eliminated shoddy hotel ethernet service problems, inaccessible hotspots, etc. Our people can get mail and grab files from our servers from anywhere: in the cab on the way to a meeting, waiting for the gate at the plane, etc.
We deployed Berrys to the company about 5 years ago. It was a phenominal investment. Some use it as their primary email device: depricating their mail client, while others use it as a touchstone: they need to get to a computer. Add to this the convenience of having their calendar and contacts realtime synchronized, they can accomplish CRM anywhere, anytime.
We've been living with this tech for years now. It has never been a question of ROI as much as SOP. This is the landscape in which we work. This isn't a competative edge, it is the cost of doing business -- as much so as having an office space and computers.
