I hope that people here (especially Ragnar), in discussing how to provide a platform for faster typing, will consider and compare qwerty-enhanced-with-AutoText, as in the Blackberry.

There are a Brainstorm entry
(http://maemo.org/community/brainstorm/view/autotext/)
and a thread
(http://talk.maemo.org/showthread.php?t=31909)
about it.

In real-life usage, I bet that implementing autotext would have the greatest impact.
