One of the questions I see the most in forums and sites like Yahoo Answers is : "What is the best Linux distribution for beginners?" or "What is the easiest Linux distribution?"
Well, unlike what you may think these questions are not that easy to answer, as the easiest Linux distribution is not necessarily the best for all beginners because other factors like the availability of support and applications is also a factor to take into account.
For the title of easiest Linux distribution for a beginner I would suggest Linux Mint.
Linux Mint is actually based on Ubuntu Linux, but simplified for users coming from Windows. The user interface has been tweaked to look and behave more like Windows. Most common applications like the flash pligina as well as video and audio decoders come pre-installed with the base distribution, meaning less things to configure for the beginner user.
