My first phone was a Nokia 3310, and the typing experience on this was significantly better — despite it only having 10 keys. I’m not saying it was faster — although it might have been — but the enjoyment of typing in words was so much higher because I could literally close my eyes and just press the given keys a deterministic number of times to arrive at my imagined word.
The experience of typing on a touch screen, by contrast, involves constantly looking at the screen to both see if you hit the right virtual button, and also if Auto-Correct tried to be “smart” and changed the word you actually typed to something else.
sigh. Oh how I yearn for the physical phone keyboard.
