I think 2012 was a great year for Linux. More and more people hear about Linux everyday and more and more people continue to experience problems with Microsoft operating systems, and more and more people continue to search for an alternative to Windows. The path leads down to either using Linux or purchasing an Apple computer. Both, in my opinion, are excellent solutions. Sorry, I'm not a big fan of Microsoft operating systems. Although, Windows XP isn't all that terrible of an operating system, but Vista, Windows 7 and Windows 8 I really don't like.
If you are curious about Linux and want to learn more, there's literally hundreds, thousands of articles, blogs and pages about Linux. I guess one of the biggest challenges is figuring out where to start. In my opinion, the first step is learning more about what Linux can do for you. Lifehacker published an article that I think will give you some great examples. Creating a powerful home media server, turning an old computer into a network backup server, building a low-powered home file server and simply surfing the web with an amazingly efficient, yet older computer are a few things you can learn about.
