I seem to remember that a good pencil has lag on the order of 1ms (how long it takes the tip to settle out after high speed motion), but I don't remember where this number came from, so it's untrustworthy. I always view the IBM selectric as "beyond the horizon" in terms of responsiveness: that's 25–30ms.

Not sure what lag there is on actual pencil, but there's this somewhat famous video[0] from Microsoft Research, where they test various values of input lag on a touch screen, and demonstrate that even 10ms is noticeable - but 1ms is about enough for it to feel instant. With 1ms lag, drawing on a tablet seems to feel just like drawing on paper (I personally haven't had an opportunity to test a tablet with 1ms lag, so I can't tell). -- [0] - https://www.youtube.com/watch?v=vOvQCPLkPt4 https://www.youtube.com/watch?v=vOvQCPLkPt4
