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. Fairly large touch screens do have their place tho - take the POS systems in some bars and restaurants for example.

We're going to have to learn to wiggle our ears.
