The problem is that redundant users still only buy 1 person's worth of software. This might partially explain why we keep reading articles about how this or that developer has made more money off of their PS3 version of a game vs. their 360. Then again, those articles might have nothing to do with redundancy at all. Your situation is different. You use both your 360s. I'm talking about people who buy 1, it breaks and then instead of getting it fixed for FREE, they instead buy another 1 for $200 or more.
omg, stop making it seem like getting the console fixed for free is such a great deal. It takes WEEKS of downtime for you to recieve the system back and begin playing your games again. Maybe for a casual gamer that is no big deal, but many hardcore gamers wouldn't be able to survive for several weeks without their system of choice. 200 for instant gratification is not too much to pay for.
