That's fine if: a) you can get a seat; b) your seat affords you enough elbow and leg room to type; c) your ride is smooth enough to type. My current commute includes a 40m - 1h bus ride. I get 'a' every day; I usually get 'b'; 'c' is pretty rare. When I used the train instead 'c' wasn't a problem, 'a' was difficult and 'b' was virtually non-existent.
