Novelist Pens First Book on Smart Phone

This is an amazing story about author Peter V. Brett who has published his first fantasy novel which was written almost entirely on his HP iPaq phone, typing with his thumbs! He reckons about 60% of the novel was written using the smartphone, sometimes on the train to work, in the queue for the bank, or sometimes just sitting in the park. He doesn't like using a laptop!

If Mr Brett did indeed scribe 100,000 words of his novel using his smartphone, does this mean that students can be expected to write essays, reports etc using similar technologies while commuting home at the weekends?
