That's disappointing. That means that OpenGL support in Snow Leopard is really no better than Leopard. Leopard already had full OpenGL 2.1 support for all discrete GPUs in Intel Macs and partial OpenGL 3.0 support. nVidia has already released drivers for the 8000 series and up including the 9400M that has full support for OpenGL 3.1 in Windows and Linux. If I'm not mistaken, OpenGL 3.0 is important because it makes it easier to share data sets with OpenCL on a GPU so they can work nicely together. I'd imagine it'd be valuable for say fluid modeling applications where you want to crunch the data and visualize the flow (really OpenCL's bread and butter for the professional community) or for games with physics and graphics. It's interesting that Apple is pushing so hard for one but neglects the other.
