Large business environment, yes.
SME, it's not such an issue when you can count the number of servers on one hand.
I'd agree here.
Our place is relatively small, so we follow the names I mentioned above, but each of our desktops has a 40GB as a share. My boses machine is called the 'thelegend02', and our room booking system/resources management service is called 'thebigcheese' (forgot about those too...but they're workstations...)
