It depends where you live. If I drive into my company's suburban office (which I have rarely done for the past few years), I'm about a 25-30 minute drive. If I take the commuter rail into the city to go to another office, I'm about 90 minutes door-to-door between drive to train/train/subway/walk. I don't mind doing the latter now and then, but if I had to make the choice most days, that wouldn't be my pick.
I did commute into the city semi-regularly for about a year once. It really wasn't sustainable over a long period even though I didn't need to do it every day most weeks.
