Windows may be best _desktop_ operating system for enterprise, not _best_ operating system. Subtle difference. OSX and Linux are not bringing desktop OS to tablets and touch laptops, because nobody wants desktop OS there, everybody wants tablet optimized OS. C# may be syntactically best language for enterprise, but it's ecosystem is lacking compared to other languages (for too long, it was use-MS-only-frameworks-and-products-land, so nobody bothers now). It is disputable whether Xbox won the game console war, but even if it did, this is a niche market. Kinect may be very unique, but we are talking niche in the niche. Surface Pro may be the best desktop replacement tablet, but nobody wants to replace desktop with tablets, just like nobody wants to replace truck with sport car.
But Borland/Imprise/Codegear/Embarcadero lost track long time ago and is currently only relevant to a few enterprise customers.
Could you tell me what you are measuring to reach that conclusion? Last I looked, the only category where the Xbox was ahead is US sales, and even there, they were only marginally ahead of the PS3.
PS3 total sales: 75 million units
Wii total sales: 100.04 million units
nintendo ds: 153.93 million units
nintendo 3ds: 32.48 million units
sony psp: 76.3 million units
sony playstation vita: 2.2 million units
sony psp go: not many
There's pretty much always been multiple competing consoles, and I don't think Sony and Nintendo are ready to throw in the towel.
