I am a professional writer, and I write on the computer (not paper), so I only type about 60 to 70 WPM and that is as fast as I have to go. I understand people can type that fast, I just can't fathom myself doing it. I don't think I need any more links to HHKB vids, I have seen most of them and I already bought one.
I am not too impressed with the di*Hell*no-vo keyboard or wireless keyboards for that matter. For what they charge, you could buy any number of mechanical keyboards either new or used with plenty of life left in them.
That Majestouch whatever looks better everytime I see it though ...
