What you are looking at here is the Wacom Bamboo Stylus, and it is meant to be a stylus for a Wacom tablet. If you don’t know what a Wacom tablet is, then you should probably read some old entries of my blog, like this.
Oh, you can also use a Bamboo Stylus on anything with a touchscreen, which really helps on tablets and smartphones. I have used Styluses before, and the Bamboo is 25 percent narrower in diameter.
You can use the Bamboo Stylus on Wacom’s Bamboo Paper, the Penultimate, as well as Autodesk, Sketchbook Mobile, and I’m sure much more. If you want to get in on this stylus action, feel free to lay down $29.95 at the Wacom site.
