Some discussions about security made me wonder which OS most people use. If you use multiple Operating Systems, choose your favorite one. If you don't know, don't answer the poll.
the most secure os is Dos 
no internet no nothing. Its is a very long conversation about what is secure and what is not.
i use 4 distros of linux among ubundu, suse,debian,unbreakable linux
, windows, and some times a mac (!). NONE of these is secure. For anything of them to be secure it would need an educated user.
if you understand what i am writing you will get my point.
