Personally, I don’t have any problem with Pystar. As long as they are selling legitimate copies of the OS, they are free and clear as far as I’m concerned.
Microsoft's business model is to sell licensed copies of software for use on "IBM compatible" PCs. Apple's business model is to sell computer systems - software license and hardware, as a package deal. The Apple model allows the company to profit from its development of software without having to charge big bucks for upgrades. In the present instance, only $29 for Snow Leopard as an upgrade from Leopard (tho Apple makes no provision for preventing SL from loading on an old Mac without Leopard on it).You want Psystar to succeed in destroying Apple's business model, forcing Apple (so you think) into the Microsoft model of software license sales, with Apple's Mac line of hardware becoming uncompetitive and falling by the wayside. Well, yes, it would do that - but there is no necessary reason why Apple must remain in the personal computer operating system business at all. Apple is making big bucks on smart phones and iPods - and would quickly start losing money on developing OS X under the Microsoft model rather than its own model. The probable result of what you are wishing for is not more competition for Microsoft, but the end of aggressive development of OS X.
I simply don't see a legal or moral problem with them taking software they've bought and loading it up on whatever hardware they want. I'm absolutely opposed to the concept of these companies claiming (when it is convienient to them) that you are actually licensing rather than buying it. The entire idea flies in the face of the doctrine of first sale, which was thankfully fully adjudicated when the US was a Republic was goverened by reason and rule of law and prior to the US becoming a corporatist state where copyright has essentially become eternal.
