Keyboard > iPhone > Treo > Pen > Newton > Palm

If it’s not already clear, this isn’t a particularly scientific experiment. If you performed the same tests you’d probably come up with different results depending on your proficiency with the various devices. But here are my results [...]:

  1. Keyboard: 3′ 14″
  2. iPhone software keyboard: 4′ 56″
  3. Treo hardware keyboard: 5′ 23″
  4. Pen and paper: 5′ 33″
  5. Newton MessagePad: 9′ 17″
  6. Palm Graffiti: 12′ 16″

Interesting test. It’s a personal benchmark, not scientific at all, but still an interesting overview.
The most surprising part for me is seeing pen and paper so slow…

Cristiano de Nunno - Glorfind3l:

Yeah, the "traditional" handwriting time surprised me a lot too but at the end it's not so strange if you think. Let's take a practical example.
To write an "A" on a keyboard you just move one finger down to press the "A" key, while to write an "A" you have to do at least two draws, doing at least 3 movements with you hand.
In cursive handwriting you gain some minor speed increase, but the movements to draw different characters are always a lot more than pressing keys on a keyboard.
