Do you have different partitions or virtualization? and why?
I see that for my hardware Mac OS X is the best OS, but Linux is fun and free, and the best drivers and games are for Windows.
Tri-boot is cool but it is difficult to share the files among the OSes, maybe the best configuration is to use Windows as main OS (for tv card driver and the overclock utility) and to keep Linux and Mac virtualized.
Will XQuartz work in VMware or VirtualBox?
