I 100% aggree on that ..
Computer users learned over time, that you have to umount a memory stick, before removing it, otherwise you risk data losses. 
I'm 100 % sure without a message "you can remove the key"  thin client users will be confused.

And how can a user be sure that the memory stick still get still not used by an other program?

* umounting floppy disks
What is the issue with floppy disks? When I enter a floppy disk on a thin client (feisty), the floppy icons appears. I noticed that nautilus shows the floppy disk on his right side. But when I select umount, I get this error message: 
#Unable to unmount the selected volume.
#umount: /media/user9/floppy0 is not in the fstab (and you are not root).
Is there is also no need to unmount a floppy disk? Sorry that I come with floppy disks, but it is still imported for us, because 95 % of our users can't effort a memory stick.
