The actual travel time is maybe a few minutes more than driving, but I usually get to the stop like 5 min. early, and have to do a few minutes of walking.
I have a free annual pass from my place of employment. (A university, where the students also get free passes.)
I don't have to own a car, so that saves me a lot.
I like it fine. There are times when I enjoy it -- the light rail here is still a bit novel to me. Mostly I take buses though.
Occasionally it could be a bit cleaner, and the riders could be a bit less smelly. Sometimes it's difficult to get to a specific location, without transferring. But for the most part it works out. EDIT: Also, there's no late night service, like after midnight. Not that often a problem, but sometimes.
