Oh, there's no comparison.. but it can be informational overload if you aren't familiar. That's why I suggest setting up a test environment on another computer or VM. Even (if you are adventurous and have the spare cash) getting a small VPS from DO or LiNode and just practicing with it in a real internet environment, and wipe it and redo it every so often.
It is a laptop and I am going to be building a new computer within a week. I want to do it on the new computer and I don't want to have to set it up again. I will do it as soon as I have the new computer put together and set up
