MEPIS!! Woo hoo!! Well, in my personal opinion it's the best. I've been searching for an OS to meet my needs for awhile now after Windows finally took a big crap on me. Mepis is by far the best Linux distribution I've come across. It comes with more out the box than the top 3 (Ubuntu, Fedora, and Mandrake). With 1 CD you can test it out live, and while in live mode you can install it! I was surfing the internet while it was installing!
It comes with java, flash, mpeg support, mplayer, Azureus, Real Player 10, nice games, nvidia card support, and Acrobat Reader! Installing other programs with apt-get is an ease, and because it's .deb based, you have more available to choose from than you would have in a .rpm based distro. Woot. Cinematography is finally happy. ^_^
