Acela rocks! I can show up 15 minutes prior, not get strip searched or hassled, relax, get drink and food and I have 120v AC at my seat for work. Oh, and it's fully reclining business class seat and I can't touch the one in front of me with my feet. Right now Acela is $90 each way between NYC and DC and takes a little over 2 hrs for the trip.
Since I gave up flying for a living, I never fly north of DC anymore.
