I like that it will sync all my files from multiple devices (including smart phones) at once which makes backups much simpler than if we were only using one device as backup storage mediums are spread out over several different locations throughout our office.
The software has some bugs when trying create new folders but this happens infrequently so not too big an issue there either! It's very easy to use especially since most users can be trained relatively quickly by having someone walk them through how everything works before they get started creating their first folder/file etc..
