I use the bus as Plan B for my commute. I won't say it's the highlight of my day, but it's not bad at all. My ride is 20 minutes, and I chat with the driver (same guy who plays leaf frog with me when I ride), and it goes fast enough. I might feel differently if it were a longer trip, and haven't taken an intercity bus in the USA for over 30 years, so can't comment on how that would be. (but given how air travel is these days, I can't imagine it being any worse).
