I suspect the bit about the keys for "typewriter" being on one row for salesmen is a myth, but I'm prepared to be convinced otherwise.
What IS true is that the key layout was deliberately designed to put commonly-occuring letter combinations far apart to avoid a clash of physical keys. So the keyboard layout is designed to slow down typists!
There are alternatives but none have caught on....
