Click to viewHere's the video review for the new Wacom Cintiq 12WX, a tablet that allows you to draw directly on the screen with extreme precision, great feel and amazing results (even with butter fingers like mine). The Cintiq 12WX is probably the best peripheral I have ever tried. If you are not a professional illustrator or photographer, you may want to get one. If you are pro, however, you will be wondering why have you been waiting for so long for this 12" wonder.
(UPDATE: Since there were so many questions in the comments, I've updated the post with new information)
Pressure-sensitive displays are common now in the Windows Tablet PC world, but not all tablet displays (or as Wacom calls them, interactive pen displays) are created equal. The 1,280 x 800 Wacom Cintiq 12WX has 1,024 pressure levels on both the pen tip and the eraser, with a +/- 60 tilt sensitivity. The difference is clear from the very first time you fire up Painter or Photoshop. The pen smoothly reacts to your actions like it would in the real world. The only thing you will miss is the drag of the actual pencil or pastel on paper.
