By the way:

IHMO virtualization, which originally came from Mainframe world
somewhere in the 60's/70's now has reached mid- and low-end area
and has the potential to become a primary building block of modern
OS design (especially when used cooperatively): let several OS'es 
(as demanded by certain applications) run under some hypervisor
and move the hard iron works to it (guest OS'es would only cope
w/ virtualized devices or those attached to a standard bus like
SCSI or USB).

In the long run, this could also solve a lot of driver availability
problems: hardware vendors just have to make sure that for the
host/bare-metal OS'es drivers are available, and all others would
just talk to the host. Certain OS'es could even be designed to
exclusively run under a hypervisor (as known from Mainframe world).
