that is why i work on a mac. the g5 for the past 4 years gave us 64-bit memory space, worked great for us video editors, and there is no fall out between a 64-bit Mac OS X and a 32-bit. Acutally there is all this talk about dual binary (intel. ppc) for the past year but apple has been doing this since they had the G5 out there, 64-bit or 32-bit. now with the intel core duo 2s people can use more then 4GB of Ram… 64-bit CUP and all
cheers
