I first mentioned Scott Thigpen and his Artsy Fartsy Weblog a few weeks ago because Scott is using his Toshiba M200 Tablet PC to produce the great sketches he has available on his blog. He has gotten some good feedback from other artists who currently use graphics tablets as opposed to Tablet PCs and he has responded to those questions in this post on his blog. Check out Scott’s sketches done on his Toshiba with Alias Sketchbook Pro here.
I have a Wacom Tablet, albeit a cheaper one. I think the Tablet PC runs circles around it. That’s my opinion, mind you and not the final word in "digital sketching."
