Microsoft is 0/3 in the console market with many billions of dollars wasted on the fourteen year long Xbox fiasco.
The first Xbox was an overpriced bunch of desktop PC parts thrown in a big ugly box and was dumped by Microsoft due to its failure in the marketplace.
The second Xbox:
* Was rushed out the door a year/year and a half early to try to pad out its installed base numbers
* Had the RRoD fiasco that inflated its installed base numbers by tens of millions of units
* Cost 200 dollars less than the much more powerful PS3
And despite all that Microsoft still came in last with the Xbox 360.
And now Microsoft is getting utterly crushed by the PS4 in worldwide sales.
To describe the Xbox as anything other than a monumental failure for Microsoft is delusional.
And, no, the Xbox One hasn't 'sold 10 million' - its worldwide installed base numbers are in the 7-8 million range. The Xbox One has been bombing so badly in sales that Microsoft will not admit to its actual installed base numbers.
