And the fact that it has a burning rivalry with apples OSX.
OSX
Apple's mobile operating system is very similar to androids in terms of interface. Unlike android OSX tries to be more user friendly by limiting the amount of complicated customization options. Different versions of OSX have been used in all of the iPhones, iPads, iPad minis, MacBooks, MacBooks Pros, iMacs and Macbook Airs.
X Box one
The Xbox one has a total of three operating systems, 8 gigabytes of ram and an extremely efficient interface the X box one's operating system(s) try to accomplish the goal of an all purpose entertainment system.
PS4
Unlike the X box one the PS4's operating system focuses more on the gaming experience then anything else it breaks the game up into different parts that can be accessed from the screen rather then needing to enter the game then accessing those parts. Un fortunately this means that it will be hard for developers to make there software compatible with the system.
