How user friendly is it? I have some spare time and was thinking about downloading it onto my desktop computer (which I don't really use anymore) as a side project. My dad is a computer engineer and says it's "user friendly" enough, but his definition of that is probably way different than most peoples'. I have a basic knowledge of computers, and know my way in and out of Windows. Give me any pointers or advice I should know about Linux. I will be using the one that you can download from their site. Thanks!
