I have a 0-9 keypad, but I can set it to predictive text and I know even things like when I type "Kiss" (lol) it comes after "lips", "me" comes after "of" and so on. I can type fast and one handed.
i can't do it downtown or on campus, because this city simply has too many bikers and asians. On the highway though i'm pretty much always either texting or on the phone. Supposedly it's illegal here now, but i don't know anyone who's been pulled over
