I am still a newbie and really want to rid the world (starting with my family) of Windoze.
I tried a distro (that recently changed its name) which is supposed to be good for newbies and it very nearly sent me away from Linux for a long time.
Just before the Linux community saw my back, I tried Ubuntu (after reading much good stuff about it) and now I'm hooked. It's got a fantastic dedicated community and forum
but mainly, it just works. I've had some niggly little problems, like setting up the serial modem, but found simple step by step instructions in the forum (search first!!) and had it sorted in minutes, as compared with 3 weeks of frustration with the other distro. Installing new applications is a cinch, forget RPMs.
So, try Ubuntu. It may not be for you, but I'd be surprised. If you prefer KDE desktop, try Kubuntu. Same distro with KDE.
Hope this helps.
