Re: Nothing like having your work day extended a few more hours
Ditto. I'm forced to use Office of one sort or another at work (generally to read stuff generated by other people, since I can usually get away with something relatively sane, such as MediaWiki, for documents I generate).
But for my academic and personal stuff, I've always used OO or LO for spreadsheets and presentations, and LaTeX (usually via LyX) for text. HTML I write by hand in vim and check with a validator. I've never, ever missed Office in this context. Not once.
