Display Postscript, however, is the NeXT imaging model.  The Graphical User
Interface, NeXTStep or whatever you call it, is something new, created at NeXT.
Display Postscript only defines the graphics language used to describe any
particular screen display, not the display itself.  So Apple, if they felt
inclined, could certainly attempt to sue NeXT over the NeXT GUI.  I think they
would have a problem with that, certainly; the MicroSoft case did involve 
software previously under license from Apple, NeXT software does not involve
Apple.

Sure does, you could even run it on Amiga if you chose.  That's not what's 
meant by Device Independent Graphics, however.  Postscript is device 
independent in that the program creating the an image doesn't need to know
anything about the device it is creating the image for.  A wordprocessor
could create a postscript description of a page, and display it very nicely
on a screen.  That same description sent to a laser printer or a photo printer
would print at the appropriate resolution of those devices.
