It really shouldn't be the web designer's job to pick a width that the content will display as and impose that unilaterally on everyone. That way it's easy for everyone to make their own choices. If you want 27" wide lines of text, go ahead and full-screen that browser and have at it. If you want the text you're reading to take up less horizontal real estate than that, then you can easily make the browser itself as wide or narrow as you like.
