I've been thinking about getting Linux and using it on a USB but I'm not sure how it will work on a USB as I have never used Linux before. I wanted to get Linux so I could play games on it and not have any of the games interfere with the host computer I'm using. Would it be possible to use a USB that has Linux on a Windows computers? Well, I think that the Linux runs off the USB but I'm not sure. Also if I have a USB with a U3 system is that the same as having a Linux system?
