That is what I thought.  Thanks for the clarification.

Its amazing though how OS/2 PPC looks and feels just like Warp3.  Its a 
shame it was never finished, but seeing the following I understand why IBM 
decided to pull the plug.

And that was back when a billion dollars was worth something.  This is more 
than I had heard before, but I suppose it depends on what people consider 
included in the development and from when.  Wasn't Taligent started to work 
on that project?

OS/2 PPC is still an amazing piece of work.
