There are dozens if not hundreds of them.  U: is mapped (by our IT department)
to our Unix login (Unix/User, hence U:) directory. 
Other things are not our login directories and it would be wrong to map them there.
Similarly, we would not want to require each user to duplicate a bunch of
drive mappings on their desktops (or symlinks in their unix login directories)
Thus, We use UNC paths for these other locations.
For example, I would access your login at \\sashq\root\u\eliz 
whereas it would be U:\ for your, and you would see mine
at \\sashq\root\u\sasdjb

This has all evolved over a period of years...
