I can do that! I just need to talk REALLY SLOW!
I have sometimes practiced typing by listening to TV and typing - somewhat abbreviated - versions of what is said. Not really very good at it, but sometimes I get a good run going.
I sure could never do 150 wpm! My best is 93 on the TB. But it is people who can type really fast that I'm most interested in seeing how they do when switching. I have little doubt that the TB is as fast or faster for most people once they adjust, but don't know how that may work out for those with extreme speed. At least anyone over 100 on a regular keyboard.
"Soft keyboard"? Does that mean the software keyboard, ie, typing on glass? That would be pretty good to me!
