No, really.

When Satomi Nakamura uses her cellphone, she has to be extra careful to take frequent breaks. That’s because she isn’t just chatting. The 22-year-old homemaker has recently finished writing a 200-page novel titled “To Love You Again” entirely on her tiny cellphone screen, using her right thumb to tap the keys and her pinkie to hold the phone steady. She got so carried away last month that she broke a blood vessel on her right little finger.

“PCs might be easier to type on, but I’ve had a cell phone since I was in sixth grade, so it’s easier for me to use,” says Ms. Nakamura, who has written eight novels on her little phone. More than 2,000 readers followed her latest story, about childhood sweethearts who reunite in high school, as she updated it every day on an Internet site.

This is astonishing in so many ways. First, there is the reality that millions of twenty-something kids can type on cell phones better than on a keyboard. I have a hard enough time typing out a simple one line email on my iPhone. The age gap notwithstanding, that fact that legions of people are tapping out content on their mobile devices shouldn’t make it so amazing that real readable content is being generated. I suppose I just assumed that most of the cell phone content in the world read like this:

wd u lk 2 go W me 2 go gt <) 2nite?

And this cell phone book biz is the real deal. Sales of mobile-books are expected to double to $200 million this year. Two Hundred Million Dollars. Incredible.
