Off the top of my head and out of my close friends and family this is the break down of the last 3 years.
Sister - 2 computers, 1 console
Friend - 2 computers, 2 consoles
Friend - 2 computers, 1 console
Friend - 2 computers, 1 console
Friend - 1 console
Friend - 1 computer
Me - 1 computer but you could basically say its been 3 since I've had multiple motherboards, cpus, and video cards. And no consoles.
Note the multiple computers from my sister and friends were all 1 laptop and 1 desktop but they all got something that would be able to play games well.
