I am sure most write down taxi instructions? I do in short-hand, so I can read them back correctly and to have the clearance in front of me if I should forget some of the details.
If it is a "simple airfield" with few taxiways, I might use the MCDU scratch-pad
The quality and delivery of speech from ATC at JFK has been noted - always my least favourite part of a long-haul trip !
