• 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
  • Believed to be a fork of FreeBSD
  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 ?.
