You really use the eraser? I just keep my fingers hovering over the E and B keys .
I don't even really like the eraser, it just gets in the way. Sometimes I'll be photoshopping and my tablet stops working, and it takes me a minute to realize I'm holding the damn pen upside down . They should make a pen with a nib on either end for absent-minded people.
Yeah I like the eraser lol... I have this automatic "flip" response when drawing because I work a lot with classic 2B pencils that have the eraser on the end. I loath touching the keyboard while using my tablet, I have all the important hotkeys mapped to the tablet buttons and sliders (change brush size etc).
You can change the eraser end to a nib in the WACOM software as well... at least on the Intuos 2 and 3 series I can... not sure about the Grapphire or Bamboo tablets, but it's just software based so I would assume that you could.
