I just got my used burgundy Dvorak TouchStream in the mail last night, and I'm just getting used to it today. I'm typing on it right now, with many corrections.
So far my left hand is always spot on; 99% of my mistakes are on the right, and especially involve the 'l' key, but also occasionally every other key on the right. I already touch-type in Dvorak, so it's not the layout. Weird. Anyone else had this experience?
