Honestly, they probably wouldn't care nearly as much as you do. Hell, I bet that if you walked into an apple store and told them you could get your brother/sister/aunt/cousin to buy you a mac under the student discount, but that you would rather buy it yourself for convenience purposes, they would let you do it. I bet that happens every single day in apple stores all over the world.
Apple knows full well that not everyone who uses the educational discount is technically eligible. It's a marketing gimmick. If they cared at all, they would require ID before the purchase is made.
Thanks you for your input. I just got off the phone with an Apple rep. She said that I would be eligible for an education discount for having an uncle who works for a University. But having that said, I do not have anything in writing allowing me to do so. That being said, I will be purchasing another rMBP in the very near future, maybe when ML is already pre-installed and the problems have been patched.
