Laptops and the Golden Ratio
Laptops have lately gone widescreen. In spite of the trend, I bought a second 12.1 x 10 apple; it's just small enough to fit in tight places, and almost square. But rectangles, according to the ancient geometers, are better than squares. And a 13.3 x 9 rectangle is closer to the golden ratio than a 12.1 x 10 rectangle. (If I were a real Johnnie, at this point I would do the math.) So perhaps my inclinations are untutored, and the designers have caught on to the true nature of Beauty.
