Welcome to LQ!
You're right about having a play around first- you don't want to lose crucial data.
Fedora is fine for a newbie- remember that you don't have to pay for quality. Of course, it's nice to support open source products monetarily if you can, but in the open source world, it's not a case of "pay more = more quality" or "free = bad".
Also, this (LQ Suggestions and Feedback) isn't really the right place for this question, I've reported it to the moderator to be moved to the right place. Don't worry about posting this again in a more suitable sub forum, just let the mods move it to where it should be so those who know a bit about your question have a chance to see it and answer it.
