Just being curious... Who are you and what is your main interest to a software like MoI?
I'd like to hear your story... I hope this hasn't been mentioned before.

I am an engineer from Greece, I think MoI is the best and simplest so far 3d modeling software for my needs. I need it for special details for my building models because Revit (From Autodesk) handles objects like doors, windows, walls, roofs etc very well but it is not a general modeler. Also for some special projects like stores, office equipment etc. I believe MoI will do the job very well and fast. That's why I would use an app like MoI.
