Ubuntu
Because it's good for you.
That is all.
Edit: I have been using Ubuntu almost exclusively since starting my new job, 2 months ago. I love it. It definitely requires a little bit more comfort with the way computers work than a cotton-candy operating system such as Windows or OSX. However, once you get over the intimidation of a black terminal (and practice a little with vimtutor) it's really a very nice operating system for the up-and-coming technical elite. I'm sure once I get more comfortable with it, I may find that I enjoy some of the more "Hard Core" Linux flavors, as I believe Ubuntu is considered "cotton-candy" in the Linux world. However, for someone who is just getting their feet wet in the Dark Side Hot Tub, I'm quite pleased.
