It's odd that the article mentions two or more examples for every topic (e.g. VHS vs. Betamax, English vs. Esperanto, Macintosh vs. Microsoft, gasoline vs. steam vs. electric car). But for keyboards, only QWERTY was mentioned, with an allusion to "half a dozen other keyboard layouts that are said to permit faster typing". So here are a few alternatives: Dvorak, Colemak, Arensito.
