Re: Which linux to use?
All of these suggestions are extremely vague and for the most part, useless. Before we can actually recommend you an Operating System, we have to know what you are going to primarily use it for and why you want to learn it, IE: Desktop os? Web server usage?
If you want a desktop os, try Ubuntu, if you plan on running a web server or game server from it (Not as in running one (a game server) on your laptop, but if you want the skills necessary to run this sort of thing in the future) Red Hat/CentOs is a good choice.
Of course other distros like Debian, Fedora Core are good choices if you like to get technical on what you'll be doing.
