So the mountpoint can be created on the fly, and so it is also
volatile. The system could "mkdir /media/<mountpoint>" everytime a USB
is plugged, and then "rmdir /media/<mountpoint>" when it's unplugged;
but if something happens (a power failure or something similar), then
you would need to manually remove the stale dir, or have a process do
it from time to time. Actually, some years ago it was not rare to have
such stale directories under /media.
None of this happens with a tmpfs.

I don't know, really. gvfs (the new virtual filesystem for GNOME)
mounts the remote shares in $HOME/.gvfs (which is also a tmpfs). I
suppose a $HOME/.mount could be created.
I personally don't care, but it is certainly not consistent. However,
I agree with the idea of getting rid of the /media dir, and I have not
used /mnt in years, so I'm thinking on deleting both so my root dir is
