Entropy of iPhone headphone cables (an excuse to experiment with WP-LaTeX)

Why is it that iPhone earbuds seem to tangle with so many more hopeless tangles than any other cables?
displaystyle frac{dS_{iPhoneCable}}{dt} gg  frac{dS_{genericCables}}{dt}

Of course, this whole exercise was an excuse to play with LaTeX and the WP-LaTeX plugin.

I also managed to find a nice LaTeX cheat sheet in the process.
