I agree that Apple's EULA is too strict; maybe even to the point of monopolistic dealings, but I also think that if we're going to crack down on Apple, flags must be raised about all software EULA (i.e. "Your software purchase is good for use on one computer, no copies of the discs may be made legally). However, any business that Psystar has done until their EULA was ruled illegal should be considered damages.
I know that OSX was built off of code that wasn't originally Apple's, but it's more than just an OS clone. If Linux was that easy and pleasant to use, people would be using it. Apple has refined OSX to perform well and it is a great example of what a modern day OS should be. It doesn't hang up or bog down just because you asked it to multitask, and it is extremely stable. Anyone that uses OSX with any frequency would admit, we cannot let Apple go unpaid for their efforts. Part of the beauty of Apple's products is that their software and hardware pair together seamlessly if not beautifully.
That being said, I still feel that Apples EULA is too limiting and strict, but the choice we must make is do we want to shred an innovative company who has done great things for the industry over this? I say no, but I do think some reform in in need across the board.
