I travel enough to not be confused when booking :) And sure for 3-4 hrs I would (and do) take the train, but when the hours go up (over 5 hr say), trains are not so good. When you are a frequent business traveler, you pack differently as well; no luggage surcharge, no waiting in line (priority because of points), free food/drink in lounges. For frequent larger distance travel, trains are a very poor alternative at the moment. Still, I would take them (usually, if not in a hurry which is usually not the case) if they were much cheaper (they are almost always more expensive at 5+ hr distance on the routes I frequent), but that's also not the case...
