[Trisquel-users] What are the things that Trisquel can do but Windows 7 can't?

[uedibupi]

What are the features that Trisquel has but Windows 7 doesn't? I want to know  
more about Trisquel and any special features that it has. If possible, please  
make a list of such features. I can use it to persuade people to switch from  
Windows to GNU/Linux.
