45-minute to hour-long commutes each way have been the norm for me pretty much the entirety of my 20-odd year career in Silicon Valley. For me the outliers were the folk who opted to live 2+hrs away to afford a single family home, and were still commuting in - some did it daily; some did it weekly, and couch surfed during the week.
(The other outlier was the fellow who parked his Airstream in the back of the company lot until they told him he had to move.)
