Virtualization will be huge in the future, probably we will have common desktop hardware with bare metals hypervisors implemented directly on the hardware in the next 15 years or so, virtualization is already used in datacenters, network appliances and used extensively in the "cloud", how will we use it in the desktop is still open, but I do believe the first application will be running legacy application on modern operating systems and security.
