Wacom, known for its pen-based drawing tablets for traditional PC operating systems, has unveiled its new Bamboo Stylus for the iPad. The Bamboo Stylus features a black and silver design, a satin-textured metal body, balanced weighting, and a stylus tip that’s 25 percent narrower—6mm vs. 8mm—than most competing solutions. Wacom’s Bamboo Stylus is expected to ship in mid-May and will sell for $30.
