Happy Birthday, Cursed Typewriter

So why isn't Sholes the patron saint/bogeyman of starving writers everywhere? From The Writer's Almanac:

On this day in 1868, the first typewriter was patented by Chistopher Latham Sholes. It only had capital letters and it took up as much room as a large table. Typists didn't know if they were making errors because the paper was inside the machine. Typewriters were slow sellers at first, but Mark Twain bought one almost as soon as they came out, and in 1883 Twain sent the manuscript of his book Life on the Mississippi (1883) to his publisher in typed form, the first author ever to do so.
