It's coming out April 24th, Duo is both stylus and pen, check out http://www.wacom.com/en/Products/Bamboo/BambooStylus/Duo.aspx I may cancel my order for the Bamboo solo . . . my worry with the Duo is the cap isn't on the pen securely so when it's clipped to a bag or shirt pocket, and you pull the pen out by grasping the cap the stylus can fling to the ground and get damaged. The cap isn't screw-on, it's held by friction (at least that's my conclusion looking at the pics) via those black rings. There are two black rings on the pen end, and one ring on the stylus nib end.
