OpenGL not usable for casual systems?
Any moderately new computer can run a program OpenGL however cannot with DirectX (version 9) and directx is only for windows (and xbox ;))
In my opinion opengl is the best option for the casual market. It is multiplatform and it needs less hardware to work.
Example:
My macbook (not pro, with integrated graphical chip) can run Age of empires III (OpenGL MAC version) but cannot run Age of empires III (DirectX version under Windows XP)
Other example:
To in my macbook under windows, blitzmax+opengl run OK but DarkBasicPro (sorry ;P) DirectX9 don't run.
