i think 1 hour is a bad commute. I think a "reasonable" commute is half hour or less, but I know that many must take on an unreasonable commute due to other factors in their life.
My husband is one of those people.. We moved here from across the country many years ago to his job, which was in the FAR, FAR out exurbs. After about 8 years, that job ended and he looked for a new one, and ended up getting hired for a job that is in Arlington. We considered moving closer to there, but we have kids and they are already very settled in to their school, sports, church, activities, etc. So he has an hour + commute.
