I don't condone piracy but I don't see anything wrong with what he is doing. Vista gives the user a 30 day grace period to use the software before purchasing a license.
That's great for Windows users. If Apple doesn't give people that option for OSX, then that's too bad. If you don't agree with the rules, don't use the software. Just because a license doesn't provide a rule that would make sense to you, doesn't mean you can
just pretend it exists anyway.
