I'm trying to imagine LESS than an hour's commute and failing miserably!
We've moved closer to my husband's work a few times... aaaaaaaaaaand each time he's ended up changing jobs w/in a few months. So when we bought our house, we bought close to where *I* was going to be (in school), and "the curse" struck, and I had to defer school for awhile. So close, yet so far! And then I needed to reup expired credits (darn hard sciences, with 3 year and 5 year expiration dates!!!), which meant I was NOT going to pay the university (that we live by) prices for class I can take for $500, instead. Of course, that's an hour's commute away.
Our city has no public transportation to speak of. I LOVED commuting by train (and one day, plan to again). I'm okay in the car (me time, listening to music)... but on the train one can actually READ, or watch a movie, or work, or do whatever (including changing into real clothes). It's "bonus" time. In fact, when I sell this house my HOPE is to move about 1 hour by train away from a city. I personally LOVE that commute. It's built in "me" time. When you're driving (or rather, when I'm driving), then I need added time on top of whatever the driving time is.
Traffic in Seattle is so bad that a "normal" commute is 45-60 minutes. A "short" one is 20. Heck, it takes many people in the city 20 minutes just to get to the grocery store or to drop the kids off at school if you have to go during the wrong time of day.
Obviously, the above is just my own personal preference.
