re: True but there are still millions of secretaries out there
The number of memos typed annually probably hasn't changed, perhaps even increased in the 200 years since your current keyboard was invented. It's a matter of choice, but I should point out that your current keyboard was intentionally designed so that all the letters of the word "typewriter" are on the same row, so that salesmen wouldn't have to hunt for the keys. Efficiency wasn't one of their criteria obviously.
