IMO, the amazing thing about the 360 was how they were able to successfully continue selling it in spite of having the ring of death issues[0]. I know people who would go and buy a new machine when theirs died without thinking about it twice. One even gave me their 360 when the ONE came out. Microsoft sure knows how to build brand loyalty.

He made XBox customers happy with the added extended warranty but it cost MS over $1 billion, so he was ousted. From another perspective, one can also blame him for rushing out the 360 too early, but then that's how MS was able to gain market share at the expense of both Sony (temporarily) and Nintendo.
