BBC: Total recall boosts PDA writing

The idea of remembering word patterns and connecting the dots might not sound like an easy way to write an e-mail.
But IBM researchers are betting that tracing letters on a touch screen will become the way to write on a handheld device like a PDA or mobile phone.
In tests, people have reached speeds of around 60 to 70 words per minute. While this is slower than touch-typing, it is much faster than tapping out words with a stylus.
Looks interesting.
