Missing the point
Entertaining though the comment is, and many of the replies, I think everyone missed the point, mainly because no one here seems to be able to conceptualize of writing and written work as anything but some nuisance side issue.
When I write a letter, or a manual, or a business proposal, I want it to look the way I layed it out in Word, or InDesign, or Scribus. I want the fonts of my choice, not some programmer's amateur effort at a crappy sans serif foisted on us endlessly by the technology cartels. I want images to be precisely where I placed them. I want the documents I create to not be merely throwaways with a marginal utility, but to ooze the mood, atmosphere, and aesthetics I put into them.
Until you tell me how to do all of that, and make the document portable except by PDF, there is no real argument here.
It's the same reason why Linux desktops aren't a scratch on Windows or OSx: the open source community is full of programmers who seem to never have met a writer, a designer, or an editor to understand how they use their software tools.
