Well,

i think another point is that at least with Windows Vista, Microsoft is  
not shipping OpenGL with their drivers anymore [only software emulation].  
This means that every user who wants to use OpenGL has to download and  
install a OpenGL supporting driver from his GPU manufacturers home page.

So one could argue supporting only OpenGL would not be real platform  
independent since Windows users won't be able to use it without updating  
their system.
