I never understood their business model
Despite being a mac user, I actually think this is a shame. Whatever you think of Pystar and their products, this kind of restriction on what people can sell is worrying. Remember, Pystar was selling legit OS X copies, just installed on none macs.
However I never understood why they didn't just sell PCs which were Mac compatible, with all the tools needed to get it running. Then the buyer could pick up their own copy of OS X and install it themselves (it's very straightforward).
Doing things that way would have made it much more difficult for Apple to take them down. They have largely stayed away from the hackintosh community, leaving most of the main websites alone, which is why there is so much info out there. I think that's because it would be a much harder case to make.
