You'd be surprised how sensitive we are to latency on input. Microsoft themselves did studies on it: https://www.youtube.com/watch?v=vOvQCPLkPt4

You can visibly see and feel the delay on the Wacom Centiqs and they're 60 Hz.
You adjust but it's not as ideal as there's mild tendency to under/over draw. This is probably less of a problem for a whiteboard but for art, its more problematic.

That's probably due to input lag rather than refresh rates though. For non-TN screens, input lag (generally >30 ms) tends to dwarf refresh rate differences (16 ms vs 8 ms).
Because for the old stuff.. we are talking a 1-2 second lag. 60hz vs 120hz is like 16ms vs 8ms per frame, which is not noticeable.
