Your flash drive is not an issue. 8 gigabytes shows up different if you have it on windows because windows uses 1024 megabytes to a gigabyte and drive makers use 1000 to a gigabyte.
It does not generally matter if you buy it or not(at least from the it is my right. same reason why modding a game console to allow downloaded games is also not considered to be legal. Apple charges a price based on its assumption that you are upgrading a system they sold you). the actual terms of use for the software is that it is not to be installed on a non Apple system. What you do is 100% your right, but it IS in a legal grey are, thus the comment about it.
I do see a sticky about it(and so do see your point Ijack), so, I guess questions are allowed(my bad). You are right it is kind of like running a emulation article, but banning or warning a user asking about emulators.
It is hard to try to stay 100% on the line of what is right.
Either way, TwistedFury, you have your answer that flash drive is fine.
