>Good point. I'm sitting too far from a 21" to reach the screen at the moment. Odd in a way that we've adapted to viewing/reading screens in a vertical position when the most natural is (as when reading a book) about 45 degrees.

At 45 degrees to what? The desktop (i.e. top of the desk, not to itself :)? I'd rather take it as 90 degrees to the eye-screen axis.

For books, the 45 degrees is maybe a compromise between the book being horizontal enough to stay on the table, the best angle for the light (which can be anywhere but you generally expect windows somewhere on the left, as in a classroom) and this orthogonality to reader's eyes.

Not a problem, I can do that (can even wiggle my nose to an extent, and flare the nostrils - still failed to qualify for Bene Geserit :), but shortening my beard so that they'd be visible to the camera is where I draw the line - won't do that.
