Wi-fi at Piraeus Port

We are waiting to board our catamaran to Santorini, and I discovered that the port we are waiting at has wi-fi! Of course, the boat itself is delayed by an undetermined amount. It was supposed to leave 15 minutes ago, but hasn't even arrived yet. Latest information (that is not broadcast, but can be found out upon asking) is that the boat will arrive here in 45 minutes, and will take off again whenever it is ready to leave after that. No wonder they make Internet available for free here :)
