I suppose so. But just say the next version of Windows (e.g. Longhorn) is not able to be copied, then what happens to Microsoft? I don't think that most people would want to pay the full price for the OS, and 98% of people haven't paid for XP in some places apparently. Microsoft would either lose a lot of sales to people using another OS, or they would have to decrease the price of their operating system. If 98% of people are not willing to pay the current price for the OS, then to get the same profits Microsoft would have to decrease the price by a massive amount.
