The reason I have no problem investing HK$20 for a disk is simply because in the past I have paid the full price for the operating system (faulty) and most of the software (also faulty when run under the faulty operating system). So every time they fix the operating system, do I get a new copy as a replacment under warranty? No way...more $$$$. Whatever the rule changes in HKG are I can't notice any difference in the way the stuff is openly sold.
