Latest report: Virtual PC on a 933 MHz Mac iBook running XP with Service Pack 2 added is hopelessly, hopelessly too slow. The kind of "too slow" in which you can't operate the system because it is so long between clicking and computer response to the click that you don't know if the click registered.I don't recall it being that slow before adding Service Pack 2.
