Pro Revision control
Con Mac version has severely limited functionality
Con Odd UI interaction conventions
Some conventions used to interact with the software are either questionable or simply going against what's commonly accepted. For example, right-click + drag will move around, holding down the right-click will open up the context-menu and left-click in an open space will start a new unconnected node. What this results in is constant accidental opening of context-menu then accidental creation of a new node trying to get out of the context-menu.
