They did the '
inkling' but it wasn't generally well received: a bit inaccurate and more for fun than a professional product. I suppose the fact that they've abandoned it is significant.
Actually, since yesterday I've read a couple of early reviews of the Iskn Slate 2 and it looks disappointing too. No pressure sensitivity, translating speed of movement into line thickness (work hard to produce a product that feels natural to use and then deliberately build in an artificial and unnatural effect??) hit and miss response etc. etc. Worst of all, a couple of reviewers included photos of drawings compared to what the slate 2 captured. Not impressed.
