/r/ Linux info

I'm looking at getting away from Microsoft OS's, and trying one of the open source OS's.

My question is, "Which one"? I've seen many versions on the shelves, but I don't know which is better for the first time user.
So instead of browsing the magic google, I decided to try here.

May be way the hell off here.
But I just bought a new system tool thats suppose to have all the best of (MS Outlook, Skype, Real Player, GoDaddy, Salesforce.com, Google, MySpace, Timeslips, Plaxo, ICQ, AOL, AIM, MS Project, LinkedIn, Netscape)

The Main tool is COIL, still runs off of windows, but is suppose to be much more efficient.  It's only a Beta at the moment.  I'm still messing around with it, but if it helps, let me know.

Again, sorry if I'm way off topic.
