I finally decided to try out Caligari TrueSpace and here is my opinion: (I will constrain myself and be as nice and polite as I can because no more than 8 hours of my life were wasted)

1.  I'm sure TrueSpace has many great, powerful, advanced features that could be accessed through a user interface, except TrueSpace doesn't have a user interface... it has a user nightmare.

2.  It's way overpriced.  For TrueSpace to be economically viable they would have to pay me $50/hr to use it, since I couldn't get anything done with it.

3.  If you tell me that TrueSpace just needs getting used to, I will offer you a car with the steering wheel in the trunk and tell you 'it just takes getting used to'.

4.  If you tell me that TrueSpace is free so don't complain, I will tell you 'please take my trash every week... it's free so don't complain!'

ps:  A message to all 3D companies: If you have no skill in human user interfaces please, please leave this field and go into another line of business like farming or selling shoes.
