[Trisquel-users] How many of you dual-boot ?

[aliasbody]

Hello everyone,
I wanted to make this "statistic" question a long time ago but didn't knew if  
I could do it or not, so if I can't please tell me.

My question is, I made a choice of Free Software on my computers, and because  
of this I only have Trisquel Gnu/Linux and/or Parabola Gnu/Linux on my  
computers (laptop and desktop), so I just wanted to know, how many of you  
dual-boot with another operation system by choice (for example, for gaming or  
using some application that are not free).
