OpenGL ES 2 is entirely shader based, no fixed function pipeline to fullback on, which is a big difference to using OSG/OpenGL with a fixed function pipeline based state. However, you can use the OSG with OpenGL 2.0 with a purely shader based state and if you do this the actual shaders you use for OpenGL or OpenGL ES 2.0 will be very similar. This similarity means you can prototype an OpenGL ES application in OpenGL just be using the shaders and avoiding all built in state. You can also build the OSG so that it doesn't compile in the fixed function state, something that you do when you want to compile against the core profile of OpenGL 3.x.
