There are two ways a commute of 2 hours a day of commuting can work out. One, if you can actually get work done while commuting. (That has a couple implications -- usually it means a train, not a subway, so you can get a little Internet, and there's a minimum commute length before you can actually get productive.)

Two, if a substantial portion of that commute doubles as your daily exercise, and you can enjoy it and improve your health. (Usually this means a bicycle, which brings along certain weather-related implications to its practicality. Think it works better in Silicon Valley with its mild mild climate and utterly predictable rain.)
