The Internet is great. It simplifies a lot of things, makes others cheaper, and often brings win-win situations.
Take airlines (if you have the money to actually take them). Before the Internet, you made a reservation with your agent, who had an expensive computer connection to the airline. When you got to the airport, the check-in agents, gate agents and flight crew would go insane trying to balance families, groups that traveled together, safety and weight considerations, frequent flyer priorities, etc.
