OS challenge...
Very true and very valid...
It was never my intent to battle out just the OS, I meant more so the hardware, which is the substantial difference. The fact that the better the CPUs are for PCs mean the hotter they run while as the better the CPU is for a MAC, the cooler they run. The newer Mac G5 Desktop computers are dual CPUs with very low speed fans for convection cooling. MAC G5 fans run around 1500 rpm and less, while as my P4 1.6 GHz CPU fan runs at 3000+ and still runs at about 50 C. Also how MACs have independent processors for each aspect (main processing, video and audio). PCs do as well, but they are not nearly as powerfull (except for video which is getting better). This is just my own opinion...
-CIAO!~
