*cough* ... I still - after all these years of Apple promoting 64bit computing (remember the G5?) - haven't heard whether 64bit computing makes any sense *at all* on a computer with less memory than the bottleneck size of 32bit memory addressing. Maybe my _question_ is stupid, could very well be. But if 64bit mainly is about using stuff that can address RAM in excess of 4 GB, then what good does a 64bit virtual machine with, say, 640 MB RAM do on a machine with 1 or 2 GB of RAM do?

As I understand it (and I probably don't), in these "low" memory circumstances, 64bit will only add overhead and solve nothing, really. This is not a rant against vmware, btw., I wish Parallels would also support 64bit OSs, clearly. (And I hope BootCamp will out of the box, some day, as well.) But this thread is about an iMac with memory constrictions (up to 4 GB of RAM).
