Been following a few of the write ups on this Intuos Creative Stylus that comes out in October.
This stylus is a blue tooth device and with a properly configured drawing program, turns off the conductive screen and uses the blue tooth to identify pen position and angle as well as how hard your are pressing the tip. The hope is that the pen supports a much more natural drawing style. The other feature you can see in this image is a couple buttons so you can program some standard commands onto the pen as well. A real common one would be undo, so if your first sketch line was a miss, you can immediately erase it.
