Wow. That's extremely generous of them. Thanks to the OP for posting this. I'm skeptical as to whether a power cable worth more than my headphones would make an noticable difference, but that another topic for another day.
Since this thread has 500 views at the time of posting, I wonder how many people have actually registered for this.
Well I signed up a while ago when the link was still there, so I am assuming I am one of the 100, which would be really cool. I didn't put my address in the account initially, but I have now, I hope they weren't looking for that right away. Do you think we will receive a confirmation e-mail if we get one?
