You just posted a chart detailing a whole division's profits and losses as opposed to the Xbox's. But regardless, it shows that division being a huge loser until two years after the Xbox hits, at which point it magically becomes profitable, until 2012 when the division starts pouring money into Windows Phone, at which point it magically becomes unprofitable again. This is exactly the way I described things. To recap:

"it lost money its first couple of years … and since then it has been largely propping up Microsoft's entertainment division, which otherwise would be bleeding like mad."

That is exactly what that chart shows. The Xbox has been turning a yearly profit since 2008, which means it's been turning a profit for most of its life.
