I have written while riding the MBTA from Franklin to Boston before and not noticed as much of a problem as I have today riding down to NYC on Amtrak. I need to move slowly or the mouse click will take me somewhere I did not intend to go.
I am enjoying the power plug at the seat and the additional productivity gained during the ride. The swaying and other gyrations, I'll put up with.
Have you written or typed while riding the train?
What was your experience?
