I'd love to have a Wacom Cintiq or other kind of full fledged computer that allowed drawing directly on screen. But, wow, the prices are high.
I love the Cintiq line. Pictured is the 27" one, but I also run a 21", 12" and their 1st gen 13" tablet for travel use.
It very much, in my mind, bridges the gap between traditional and digital. Now granted, I'm more of a pencil sketcher and not a painter or air brusher, so I'm sure my expectations may be less due to that.
When I can't do the Cintiq way, I use Wacom's Inkling to sketch on paper (boy I sound like a walking advertisement for Wacom).
Now, I must say, I don't use DRAW, I have it, due to their partnership with Wilcom, but I actually don't have it installed and in use on any of my VMs, I use Ai and on occasion Inkscape and Zara, but it should all be the same as far as that goes.
