Sup dude..
Very cool -- app..
Tp4, am a long time computer person, and this journey has taken me to 135wpm many years ago.. 've been at that pace ever since..
In personal xperience, Tp4 has not been able to generate --useful-- text at greater than an average rate of 30wpm.. (essays, txt messaging, work reports)
30wpm is quite an elementary speed to reach, would not take kids more than a week or two..
So given that context, would lightkey really have a meaningful impact on the computer input world ?
