Same here. I found learning vim to be easier than getting used to the nib. Would love for the nib to be effective for me. I think the nib requires to much force to push around.
I'm not sure what sensitivity I have it set at but most of the time I'm only moving the tip of my finger maybe half a millimeter at the most. you shouldn't have to press it that hard but it does take a while for most poeple to get the hang of it.
