the most functionall version of Linux for home users

What is the most functionall version of Linux for home users?

Definitely Ubuntu. Their slogan is actually "Linux for human beings".

Also, with Ubuntu, you can try it out before you install it! Just burn the files to a CD (or DVD), and switch your computer's boot method to CD. You'll boot right into Ubuntu, and will be able to use everything- if you want to keep it, you just click the install icon, it installs, and you're set!

The OS itself is very intuitive, easy to use, and has many familiarities from OSX and Windows. Try it out. It's so good, that even Dell offers it on some of it's PCs.
