I have to say i am very disapointed with microsoft right now. As most gamers, it turns into a past time, and a daily thing almostr like a digetal drug so to speak. We over the last 5+ years have had more the our share of problems with our xbox360 units. Now once again our xbox is not working, after thinking i am going to ps3 i get an email from microsoft telling me the reason it will not read our games. It is because of this update that basicly turned my dvd drive into a paper weight. Don't get me wrong I am happy that microsoft is sending me a brand new system free of charge and being that i am in college for computer foresics I have a good idea that it is no easy task to write updates to millions of diffrent system types. I can understand that, its just wouldnt you keep all modles up and running to beta test your update before releasing it as a mandtory update?? I give you guys koodos for sending the replacment first and not pulling this send your unit in wait 1-2 months get it back and then repeat crap. Yet I paid alot of money over the years not only in systems and games, but the live time too. I guess now I see how long I am not able to game while I am paying for the live time right..:( Please get it together before millions switch to ps3 even with their hacking issues..
