Graphic tablets haven’t been much popular in recent times, may be because today there are quite a few handheld devices that support direct interaction with the screen/computer. Still there are quite a few companies that manufacture a wide range of graphic tablets. Check out the humongous 17-inch Wacom based tablet from Green House Japan. Personally I had never seen a tablet of this size.
This tablet has a SXGA resolution (1280 x 1024) with a “800:1 contrast ratio and a 300 cd/m3 brightness“, which if you are wondering is really decent specs. You can also easily connect it to your PC or your Mac.
