Well, I voted for 10 fingers (8 plus thumbs?) as I am a touch typist. I used to be over 100 wpm on an IBM Selectric, I am probably closer to 75 these days on a computer keyboard with little to no tactile feedback.

However, I don't quite understand the three options. How does one type with 10 fingers? I use 9, as the left thumb is not utilized as all. Is that just me? Do left handed people use their left thumb instead of their right thumb? Does anyone use both thumbs on the spacebar?
