I find files much harder to maintain .. I don't have a fixed set of
tools that can grow,shrink them , that can span them over multple
physical disks if my initial disk becomes to small.  That can easily
snapshot them.

Also ..an unexperienced sysadmin will easily start removing big files
that clutter his filesystem.  He`ll think twice when it's a logical
volume that is in use :)
