Steven did a "blitz-comparison" of MetaEdit+ with the Microsoft DSL tools. The topic: Creating your own visual representation for you modeling language and updating existing models with this new representation.
The whole thing is a bit comical, depending on who your employer is I guess. On the other hand I think it also likely blows the socks of some people who use Eclipse frameworks (GMF, EMF etc.) to build their own graphical editors. Something what Steven does in less than 10 seconds would take them something in the order of a day or two.
A bit strange to see people even struggle with immature DSM alternatives when an industrial strength solution is available for just €150 / $190.
