Why should you care about this? Because as Microsoft and Apple lock down graphics with more and more DRM, and refuse the specifications to Free and Open Source Software developers, it will be impossible to run an alternative operating system with modern graphics. And trust me; there is not enough demand for the Big 3, Intel, ATI and NVidia to cater to this market, so don't hold out that hope.
Enter an open specification graphics card. The link will take you to a short article at The Inquirer and from there you can follow the link provided to complete specifications of the new card. It's not half bad, though still available only in a PCI interface. Hopefully, AGP and especially PCIe will be coming along soon. There may indeed be enough demand to convince some smaller company to produce these. I, for one, hope someone does.
