Heh. The ghost of Sam Clemens might beg to differ:
"Among the first users was Mark Twain, who fiddled around with it before putting it aside. Yes, Twain did become the first person to submit a novel in typed form to the publisher, but that wasn't until much later ("Life on the Mississippi,"1883) , and he didn't type it himself... it was a typed copy of his handwritten manuscript."[1]
That manuscript was produced at least 8 years after the first Remington model appeared. Although Clemens was clearly a technophile (and pal of Tesla), he considered the first models to be curiosities rather than immediate replacements for pen or pencil and paper.
