How many windows devices do you have?

In my office, how many computers runs Unix or Linux.

  • Two computers
    • One runs Linux
    • One runs macOS
    Three cellphones
    • Two runs Android (4.3 and 5.0.1)
    • One runs iOS 9
    One Tablet
    • iOS 9
    PS3 One (good old) Linksys WRG54G

    If I count all my house devices, I need to add two more iPads, one iPhone and one Apple TV.  Windows free home ?.
