Hit the nail on the head. Inefficiency, which has reached gargantuan proportions, and then blown past that, doesn't just mean page loads so slow that loading a news article takes upwards of 20s on a pocket supercomputer (whereas it took barely a second or two on a Pentium II on a 56kbps connection), all the while text and buttons jump around as assets are loaded. It also means very real waste of energy and battery degradation.
