Question: Which is the best Linux distribution for home use ? And why? 

Answer: Ubuntu is pretty user-friendly, and it's Debian based so there is a vast base of software available for it. Fedora Core is the free development branch of Red Hat Linux, and my personal favorite. It also has large amounts of packaged software specifically targeted to it's users. Mandriva is one of the easiest and most foolproof installations, and is more targeted toward the not so techies out there. Debian, Gentoo, and Suse require a little more knowledge of the Gnu/Linux OS, but are very powerful distros once you get used to stuff like command line in a terminal and such. Whichever you choose to start with, just jump in there! It's all free or nearly free, and runs just fine on an old $50 or $75 P3 that you can get off of Craigslist (or find in the dumpster if you are lucky!). Download the ISO, burn the disc, and see how you like the distro. If you don't like one then install another. Ubuntu will even mail you the install CDs for free if you don't have a CD burner or a fast internet connection.
