Yeah, I mostly agree; I did Metro North for a couple of years before switching to Amtrak. It's less flexible and a little more expensive than Metro North, but the train is usually faster and it drops you off by Penn Station which is a pleasant walk to the Google office (and like 5 minutes by subway if you don't feel like a pleasant walk).

My personal limit is 12-13 hours out of the house each day; more than that and it burns me out fast. It definitely wouldn't work for me with an employer who was less flexible about when the work day starts or who had expectations of large numbers of hours spent with butt in chair.
