I love my 10v with OS-X, but it drives me crazy when typing, because it seems impossible to avoid brushing the double-d***ed trackpad with a thumb, and whenever you do, it usually manages to select the current paragraph and overtype it.
I've got the sensitivity set to Least sensitive, and it's still a major issue for me.
I don't know if this is possible, but I'm thinking that I'd sure like to see a piece of SW that temporarily shuts off the trackpad completely, if any USB or Bluetooth mouse is attached, then re-enables it if the mouse is removed. This was a feature in 10.5, and it's tough to live without.
Thoughts?
