Our Xbox 360 suffered the red ring of death a couple of weeks ago (a series of lights indicating a catastrophic hardware failure and depressingly common), and I sent it off to the warranty place. It was an easy process, and for a moment Microsoft regained some of my respect despite being known for manufacturing a product with a propensity for self-destruction.
The Box was returned promptly, but alas, the bloody thing still doesn’t work. What the hell? I am beginning to doubt that they actually tried to turn it on, and instead just packaged it up in a different box with a cheery letter and sent it back. Off I go to lodge another repair request.
