I am a Linux geek. I have multiple distros installed on my box as we speak. Contrary to what may be termed "popular belief", it is very easy to get Windows off your computer and survive quite nicely. Well, if you're a gamer it might be hard, but I'm not so it's irrelevant to me.
My point is, considering that the maker of Windows is well-known for gaping security holes and backdoors that can be exploited by certain authoritah figures, it may behoove some to consider getting an older machine and putting Linux on it. The time may come when the security won't be just nice to have, it'll be essential.
