Legacy applications support for example.I have plenty of SME customers
who use software that are not really designed for a modern networked
environment and still relies on some old style hardware-dependent
licensing scheme. So if the workstations desktops these are on dies,
and the vendor gone out of business, they are screwed. Virtualization
eliminates this worry.

Then there is the security issue. You can fully isolate a user's
Windows desktop and allow administrative access and not worry the user
will find a way to re-enable USB ports.
