Wacom has just announced the Bamboo Pad, and it is not a notepad kind of thing. This one is pretty small, only a little bigger than the size of one’s hand. The Pad offers the user the capacity for multi-touch gestures, which comes in handy when using Windows 8.
In addition to the Pad, there is also the Stylii like the Bamboo Stylus solo and duo. The solo is your typical rubber-tipped stylus good for any touchscreen device, and the duo has a ball-point tip in case you actually need to sign something like a sheet of paper or such.
You should be able to get the Bamboo Pad in wireless ($79) or wired ($49) form in a few weeks. As for the stylii, they should be avilable at the same time. The solo is good for $19 and the duo for $29.
