The reason I bought my original Cintiq in 2007 was to use to use Manga Studio. Despite 7 years' prior daily use of a "trad" Wacom tablet, I couldn't master freehand drawing with it. The disconnect of eye and hand as you watch the cursor the screen was too much. I was far from accurate, and my shoulder would tense up in agony as I attempted pass after undone pass at long strokes.
I had a go at drawing with that same old Wacom tablet this evening as I had been using it for another job. And strangely, after years of using the Cintiq, I could now draw far more accurately than I could back in 2007. While I would never use an Intuos for all my daily drawing by choice (if the Cintiq broke and I couldn't replace it, I'd probably go back to pen and paper), I couldn't believe how much had improved.
Here's a little sketch I did, it wasn't as fluent as working on the Cintiq, but I got the sense that after a few weeks practice, I could probably get perfectly used to it.
I wonder if any other Cintiq users have had the same experience when they dug out their old tablet?
