One of the amazing things with software is that it can grow beyond the
confines and limitations that people try to impose on it. Luckily, since
we use Linux, we do not need to "limit" ourselves to only use software as
it was expected.

Consider a laptop that is used at installfests to act as a server of files
for installs, a gateway/masquerading unit, and a shell server for
multi-user access.

Also, consider hybrid systems with wine being used remotely.

Just because a person cannot see a use for something does not mean that a
use does not exist for it. You want more examples? Read on...

Our uni Networking and CS labs are this way. 1 Windows install and 2
different Linux installs. Yes, we do utilize the multi-user functions on
these systems in our experiments.

Well, we have different machines that have specific purposes. Also, there
are still some systems out there that require the admin to boot to windows

Other cases for having a bootable windows systems:
BIOS Upgrades for the system
SCSI Card Firmware updates that only run from DOS or windows
System hardware initialization for hardware that uses proprietary code to
start the hardware working so that Linux can use it
Being required by the  hardware vendor to run diagnostic software that
only runs in windows before you can have parts replaced

(many more reasons if you think about it)

I believe that user is an option to permit users to mount the device.

And if you check the option "defaults" it includes "nouser"

I include it in mine so users can mount or unmount if they wish.

The above options were created for this kind of purpose-- leverage the
existing authentication and control to decrease users' need to "reinvent
the wheel."
