Great to know! Thanks for all the details.

If you move the stylus around on the digitizer and the dot wanders, that’s a different problem. But the hand writing recognition system isn’t even being used yet.

via cable from low-power MacBook lacking wireless devices,
hence radiating no deadly EMR connectivity: see RadiateNot.Me;
plus powered by non-radiating coaxial DC cable from utility shed
where wall wart* EMR is indetectably far away
