Hey guys, Used to have a logitech roler ball, but I actuall wore a grove in my "left click" button over 8 years of service so I've been using a Bamboo for 2 weeks now in ACAD and Civil 3D. It works "OK". I find the best place for the pen when you are typing is "behind the ear" (I did board draughting what can I say???) I have to agree with mlgatzke that when trying to do OSNAPS the pen is a little "jerky" and I'm trying to avoid so much going back to a mouse. I tried the "holding it straight up" trick and it helped a little but there are still times when I'm "cruzzin" that I miss and it really takes you out of the grove if you do that 3-4 times in a row. Also the "extra" keys are not all that helpfull, in my opinion. my zoom circle works when it feels like it and the 4 buttons are ehhhh...
