Regardless of the short-term cost issues, when, if ever, does it make sense for your customers to make the shift to virtual desktops for other reasons? Being able to manage virtual desktops in a central location can bring significant savings, since it obviates the need for IT staff to administer each physical machine in person. But if virtual desktops are created as individual VMs, in the same way that PCs have been in the past, and no other tools or improved methodologies are used, then many of the same management hassles will persist. Installing software and patches on virtual desktops can be just as painful as installing them on real physical desktops. However, there are virtualization tools that allow a single golden image to be created once and then shared and/or automatically provisioned or streamed. These tools can be a management lifesaver, or at least a huge timesaver. These types of virtualization tools are continuing to emerge from the major players -- Citrix, Microsoft and VMware -- as well as a number of smaller companies, and will play a key role in the evolution of desktop delivery alternatives.

We've been fighting this desktop management battle on distributed PCs since the early 1980s. Maybe the time has finally come to win the battle with a strong combination of virtualization solutions rather than taking the physical Windows upgrade route again.
