Bus for Business?

Taking the Peter Pan bus (formerly Bonanza) from Boston or Providence to NYC has gotten me my fair share of ribbing, but it's also gotten me into the city - on time - with more regularity than the train (I have terrible luck with Amtrak). You have to time things right or you will get stuck in traffic, but dollar for dollar, I think it's one of the best ways to get into New York. Agree? Disagree?
