I personally dont have a pirated OS, i got Win7 pro through tafe with MSDN Academic Alliance. and then my Friend got a Technet liscence and gave me a pro key (Legal?) software wise, it depends usually i will pirate it and try it, if i like it i will buy it, if i dont i will remove it and delete all the files
i can't say anything about testing illegal torrents, i do it quite often with various software and games, that i intend to purchase to make sure i like them. and of course ripping my video collection to my media center pc probably wasn't legal, but i'll view my media how i choose in my own home, and i'll confess i helped my sister get every disney movie we couldn't find legally for her kids, but really many of those have been out of circulation for ages, when is the last time you saw puff the magic dragon on dvd?(if we could have found them we would have bought them)
