To your last point: in NYC it's pretty easy to do things requiring "undisturbed attention" on a 45 minute express Metro North train into the city from the suburbs. It's a very different experience from the subway.

As for the other three, I guess I could say that I'm not sure it's realistic to try and budget your time so efficiently that a 30-45 minute commute is intolerable. Many people have commutes for which that's a margin of error on how long it will take them - that sounds like a real problem.

Aside from working from home full time, what kind of commute are you looking to have, and at what distance from work? It's not realistic for most people to achieve a 15 minute commute, so 30-45 in a train really isn't that bad. If it really matters then you could do things on the train that would normally keep you from your spouse or kids at home :)

I'm one of those 30-45 minute margin-of-error folks- I'd move into Hoboken or Brookyln for a 45 minute commute in two seconds!
