brzillian, I never talked about networks, or enterprise level database servers, or anything of the sort. The PPC platform is different from the x86 platform in its instruction set and processor layout. I will not get in a speed debate, as they are near useless. But if we talk down to stability in the OS with WinPCs vs. Macs in the AUDIO world, Macs just work. Why? For the exact reasons I stated before. You seem like you are masquerading as a computer expert. But I assure you that if you do not believe the previous post then you are misguided. Its logic, just like they teach computer scientists. If you have a finite set of premises, it takes only one false premise to make the conclusion false. In this case; if you have a finite set of hardware and you test all iterations with your PCI card, then the conclusion, a stable system, is true. If you have an infinite set of premises, have fun proving that you have a stable system.
