I don't really like word-completion based schemes (the first thing I disabled on phones was the T9 typing for SMS) for the following reasons: - I type in multiple languages (both programming and human). Systems with word-completion are generally based on a single language and need a context switch and separate dictionaries. - You have to be very alert to what appears on the screen. You cannot blindly/mechanically type something and be sure that you get what you want, unless you know the entire dictionary.
