Agreed. I'd definitely say if you're only travelling across one or two European countries, between major cities, rail is definitely the way to go. It's more comfortable, safer, you're infinitely less likely to get touched up by an overzealous security person, usually takes you right to the city centre that you're interested in, you don't have to worry about Ryanair trying to extort something out of you. You also don't have to worry about airplane mode and many railways provide free (if shockingly bad) WiFi, and many routes have reasonable 3/4G coverage.
