Reason why it was redesigned!
Having seen how fast the olden day typewriter was, it was redesigned to make it a bit slower for typist but the measure reason why it was redesigned was due to the fact that it jam a lot. For example When you try typing the later TH or JK you will see how inconvenient it is.
The new keyboard was later named QWERTY derived from the letter of the first 6 alphabet in the keyboard and it actually made typing easier both on mobile phones,laptop, PC etc
