I know many of you Spec-Monkeys are on a budget, so let me recommend OpenOffice for PC and the version I'm using when I cheat on my PC with my sexy Powerbook, NeoOffice.
I know this is very, very old news for the hipsters in my reading crowd, but that's kind of my job: acting as geek translator for my creative brethren. These programs are open-source replacements for the several-hundred dollar Microsoft Office Suites (you should still send them some coin when you can, as I did once I tried it and was happy). The thing I'm loving about the NeoOffice Text Editor is not what it does, but what it doesn't do: treat me like a goddam moron and keep trying to Autoformat my paragraphs for me. All the formatting options are right there, clearly visible, the Spreadsheet works on plain-language equations ... anyway, just go and grab it and try it. For 99% of you, this does everything you want Office to do.
Oh, and I too often skip by something, never to touch on it again, so let me reiterate: the Backpack program I tried, I am now officially in love with it. In. Love. I don't need their heavier-duty program Basecamp, but I can think of a few independent publishers who would thrive on it. In theory, it'd be perfect for running a TV show, too.
