You really think RROD is caused by the consumer? The post you quoted is all about RROD, this scratch disc thing can be debatable as a big problem but RROD is a clear fault on MS part. They wanted an early release date and they weren't going to stop with just a problem they could throw money at.
I wonder if any of the other consoles have this problem, I would think not since they use a better system for loading and running their discs. Just bad for gamers having to deal with this crap even with the richest company in the world.
