If they would have had a good management they would have invested their money in the new AAA but finally gone the "Apple-way", using standard-hardware with their own portable and adaptable OS. I also do not believe that custom chipsets had a chance with the fast developing PC market and the falling prices of standard hardware. Perhaps something like AROS but of course closed source.
But at that time (I can remember myself) I am not sure if most users would have followed this route (because of the hate against PCs by many)
