Check out the video below on Swype, the next generation input for text messaging created by the same people who brought us T9 predictive text messaging that you will find in almost all the mobile phones in the world including the one that you are using now. This new method of inputing text will be out in the market soon.
"Swype will let you swipe your finger across the keyboard when writing. No more lifting your fingers, no more pressing the wrong letters. It will even have support for stylus too, so you will be kind of ice-skating on the surface of your handset. There’s predictive text too and there are lots of editing choices."
