I could T9 an SMS message while holding eye contact with a person. Right down to knowing certain words were “press buttons, down twice”.

I can almost blind type on a touch screen with both thumbs, too. However, it’s no where near as good as I was with hard buttons and Motorola’s particular dialect of T9. Towards the end, Motorola tried to get clever and start reordering the words based on MRU and it played havoc with my muscle memory.
