I'm a "shinkansen commuter" which meant before the pandemic I travelled into Tokyo on a daily basis by Shinkansen. The morning trains are pretty packed so you barely have space to get a laptop out.
But if you were doing the ~3 hour trip from Tokyo to Osaka in the middle of the day when the trains have one or two people in each carriage you might actually want to get your laptop out and do something.
