Well, I’ve got the 360 back. It took Microsoft a bit longer than expected, but three weeks isn’t bad. Of course, I had the misfortune of having it malfunction just before they acknowledged the prevalence of the problem and extended the warranty to three years. As a result, mine was only one unit being returned in a deluge of others, so this was to be expected.
Still, three weeks or so isn’t too bad of a wait considering I was dealing with what amounts to a massive corporate recall.
