Just a thought:

I always found LCDs to be too bright/stressing to look at. Looking at regular paper is a much better (and calm) experience.

ePaper, eInk, reflective display (i.e. no backlight) or whatever those technologies are called -- Are slowly coming up to speed. http://www.e-ink-info.com/researchers-make-new-e-paper-technology-designed-match-brilliance-and-contrast-paper  http://www.opalux.com/?page=technology

Now using something like that to build a "cintiq" would be awesome I think.

That would be awesome indeed. Are they fast enough yet?

Early prototypes are fast (some even faster then LCDs), high-contrast (not quite like paper, but approaching). BUT the stuff that is mass produced these days is not very practical -- AFAIK.  Their primary market is the "ebook" which is meant to be ultra-portable (thin, readable under the bright sun and near-zero power consumption).  They are like "16 shades of gray" (no color), take like a second to update a full page (updating all at once takes more power) and they have weak contrast too.

So... before this hits the "DIY" scene, we gonna have to wait.

I'm keeping an eye on this, to me, it feels like it is a "gold rush" amongst researchers/manufacturers, so we may get surprised...  Tongue

I was just about to say. I'm pretty sure that the refresh rates on those things are horrible. Sure, if you were working with an extremely thin half pixel thick line it would only lag a little. But what if you were working with a thick brush? Or worse yet, an airbrush?

Actually, the refresh rate isn't that big of a deal for drawing.  They actually have an ePaper reader with a wacom panel behind it, it's called the iRex illiad.  There has been at least one prototype of a similar tablet from Asus:

If you wanted to use something to build a tablet using ePaper then you can come very close by buying a dual mode screen from Pixel Qi:
