Hi Henning-

I have yet to use the current generation of BIM software on a project, but
from the other projects in our office using it, your analysis seems
correct.

Collaborative work is a huge problem, as there is only one master model,
unlike CAD, where each floor plan, or even partial floor plan, can be an
individual file, as can details, etc. This allows many to work on
different portions of one project at a time.  Likewise, different
disciplines can reference in each others plans to allow simultaneous work
with proper coordination.

For simultaneous work (at least as I understand it) BIM requires different
versions of the master model to be worked on and merged together later. 
Thus, conflicting edits can be made, and no one has all the current
information.

Early BIM software I used in 1993-94 was a disaster.  Basically, nothing
worked correctly.

Our energy engineers seem to be the biggest fans of BIM at this point.
