I got 2 windows upgrade keys through their upgrade program, one at the "full" $40 and one discounted for my laptop I bought a few months ago. I also got a key for windows Media Center since you can currently get a key for it for free. The rub is... I'm not ready to upgrade to windows 8 yet, and I'm unlikely to do it before the spring. It's unclear to me if the free Media center key is only valid for install before Jan 13, or if you can get the key for free until Jan 13, but can install it at any time, even past that date. anyone knows? That would also impact whether you can wipe a harddrive and reinstall Media center next year, so I'm hoping the key is good forever, the promo offer to get a key is what is time limited.
