these are good reasons and bring to mind a question.  why don't we
define a generic microkernel that all these systems can use and not
have to go to all the tricks of VM?

i now that the usual definition for a microkernel is the part that
supports all the processes that really make up the OS. but if we had a
generic microkernel then people could write device drivers for that an
all the other OSs could use that.

i'm not holding my breath on the above, so next question.  is the structure
of windows device driver environments well known enough to build a
small `container' to use off-the-shelf windows drivers on plan 9?

My reasons:
1) I hate mucking with partitions - too much chance of zapping something important
by mistake, and they *always* end up being the wrong size, regardless of how much
planning I do... With a VM, the filesystems can be in normal files, which doesn't
completely avoid the problem, but removes the day-to-day need to re-partition.

2) Machines are cheap, but (desk/office/etc) space is not. Virtual machines
don't take up real space!

3) 2 in another guise - I don't want to carry n>1 laptops!

4) I can move virtual machines between physical machines just by copying
the filesystems.

5) Compatibility with OSs I don't want to run all the time (without rebooting)

All the other things people have mentioned...
