Cedega on Linux does a fairly decent job of converting DirectX stuff into OpenGL/ALSA/OSS stuff, so a software layer isn't going to be as awful as you'd expect.
What I find most amusing is that after all the whinging from people about OpenGL being supported under a wrapper on Vista, the same thing is happening to DirectX.
Vista will do as well as XP did - either OEM with new systems or upgraded to by those who like to spend loads on their PC hardware anyway. There's still no compelling reason for the rest of us to upgrade from 2000 or XP that I can see.
