You are simply wrong about that. Apple subsidizes its operation systems via hardware sales. Most people who purchased Snow Leopard separately paid $29 US for it. Have you priced an operating system lately? Do you honestly believe that Snow Leopard is cheaper to produce than Windows 7? Price-out OpenSTEP. Compare it to any version of MacOS X. The difference is that OpenSTEP did not have Apple's hardware subsidy.
I'll keep it brief
Under the technical definition of profit, the CD costs about ~$2 to make. Even if you are pretty generous and assume he uses ~$5 in bandwidth over the years, that's still $23.
Obviously there are other costs distributed among every copy. The economy of scale is millions of dollars of investment into the OS X codebase.
Now, on that individual copy, they made a profit on the balance sheet.
If people stop buying macs and hackintosh...they lose money because they cannot sell enough copies to distribute the investment on the codebase.
My argument is, that despite his violation of the EULA (which, if you read the judgment, is why Psystar lost on so many infringement counts), and despite whatever ethical position you may take, he bought a system that Apple had no alternative for, and would have given up Mac OS before he gave up the netbook (He dual boots with an MSDNAA copy of Windows 7.) Therefore, on that one copy - where it did not affect the sale of a mac- buying the boxed copy certainly made Apple money, while not buying would have given them nothing.
Now, you may argue, if he didn't buy a netbook, he may have bought a Macbook.
But he owned a Macbook, he owned a Mac Mini, and an iMac. He wanted the netbook for the size.
Again, this ONLY holds true in cases where it would not have affected the sale of a Mac- which I'm sure Psystar and hackintoshing in general has affected. If it weren't such a pain in the ass (especially with hardware compatibility), Apple would be in trouble.
