First land, then air, and now sea. This $600,000 per week charter superyacht, called "Solemates," is also controlled by Apple's iPad device. When you rent the boat and step onboard, the captain hands you an iPad with a custom-made app that allows you to control the lights and climate systems on the boat, control entertainment systems, and even summon crew members while onboard. Pretty snazzy, though of course it's far from cheap -- anyone with enough money to spare to rent this boat probably doesn't have any issue picking up an iPad anyway.
Of course the iPad isn't the only amenity on the craft -- a wood interior fills up with natural light and has spaces for dining and partying, and there's a sun deck on top with a jacuzzi for relaxing in when you're not staying in one of the cabin spaces for 12 guests. Quite a boat to be on, indeed.
