I have tended to run into the physical memory space limitations instead of the single process memory limitations so I do not understand why Microsoft did not allow the use of PAE and more then 4GB of physical address space in their desktop operating systems. Even Vista 32 does not allow it. Was this predominantly because of marketing?
I know there are hardware and driver compatibility issues with PAE and physical address space above 4GB but the 64 bit operating systems seem to address this by requiring completely new drivers anyway or deprecated support. What was the their advantage?
