Graphic designers have lusted after Wacom's Cintiq line for years: the combination of a stylus-enabled touchpad and a full monitor makes them ideal for working directly in design suites. But thanks to their out-of-this-world price tags, most of us could only admire them from afar, settling for the cheaper Bamboo or Intuos pad.
