Lauri, I wondered the same thing before we cruised where we had internet so I think it's an insightful question. :) When you get on board you can buy some internet time. They'll give you a login name and a password and then it's just like you're at home except it's vastly more expensive since it is a satellite connection. You can check your email and log on to websites. It often works well to compose off-line and then log on, and cut and paste to save minutes. Once you get there you'll see how it works.
