Obviously (posting from a PowerBook G4) I'm not an enemy of OS X. But might I ask why, on GGE, one would attempt to use that very-definitely-desktop-optimized OS for a *server* ??? ... when several *BSD's and Linuxen run on the same hardware.. but NOT as the best of desktops there. OTOH, better desktps than 10.3.X if on Wintel/AMD/VIA. 'horses for courses' ?
